The best Wrath of the Lich King 3.3.5a addons, and how addons work on Lasthavens

Addons are a big part of playing Wrath of the Lich King. A good quest helper saves hours while levelling, and most raid groups expect you to run a boss mod. On Lasthavens the 3.3.5a client runs in your browser, so addons work a little differently from a normal install. This page explains how, and goes through every addon in the library: what it does and who it is for.

How addons work in the browser

On a normal 3.3.5a install you download an addon and drop its folder into Interface/AddOns. In the browser there is no game folder to open, so that route is closed.

Instead, the character select screen has an AddOn Library. Press Get AddOns and you get a list of addons that are ready to use. Pick the ones you want and they load the next time you open the page. Your choices are saved by the browser you play in, so the addons you switch on at home are separate from the ones on your phone or a second computer.

A few things to know:

• You pick from the library only. You can’t upload your own addon files.
• Picks are per browser. Characters live on the realm, but your addon list stays with the browser, like your settings and keybindings.
• Changes need a reload. An addon you switch on or off takes effect on the next page load.
• The versions are made for 3.3.5a. Every addon in the library is a build for the Wrath of the Lich King client, not a modern one.

How to switch on an addon

1. Open Play Lasthavens and log in.
2. At the character select screen, press Get AddOns.
3. Pick the addons you want from the list.
4. Reload the page. The addons are loaded when you return to the game.

To turn one off, go back to Get AddOns, remove it, and reload again.

The addon library at a glance

Quests: Questie

Questie is the quest helper most 3.3.5a players start with. It marks quest givers and quest objectives on your map and minimap, so you can see where to go next without opening a website. If you are levelling a new character, and with 2x experience on Lasthavens you will move through zones quickly, this is the first addon to switch on.

Boss mods: Deadly Boss Mods

Deadly Boss Mods (DBM) gives you timers and warnings for boss abilities, so you know when the next big hit, add wave or move-out-of-the-fire moment is coming. The library version includes the options window and the mods for every zone, from old dungeons to the Wrath raids. If you plan to run dungeons or raid, switch it on.

Auras and cooldowns

WeakAuras

WeakAuras lets you build your own displays for buffs, debuffs, cooldowns, procs, resources and much more, shown wherever you want on screen. It is the most flexible addon in the library and has a learning curve to match. It suits players who like to shape their interface around their class, and anyone who has a favourite set of auras they want to recreate.

OmniCC

OmniCC adds countdown numbers to cooldowns, so you can read how long is left on an ability or item at a glance instead of guessing from the clock sweep. It is small, needs no setup, and is useful for every class.

TellMeWhen

TellMeWhen shows icons that tell you about your cooldowns, buffs and debuffs, for example when an ability is ready or when a buff has dropped off. It is a simpler route than WeakAuras if you want clear alerts without building every display yourself.

Damage meters: Skada

Skada is a modular damage meter. Beyond damage done it can show healing, damage taken, deaths, dispels, interrupts, threat and more, each as its own mode. It is the tool to check how a fight went, whether you are pulling threat, or who died first and why. Groups and raiders get the most out of it.

Unit frames and action bars

DragonUI

DragonUI is a retail-inspired UI for 3.3.5a. It restyles a large part of the interface, including action bars, unit frames, the cast bar and buffs, and has its own options window to switch its parts on and off. Pick it if you want the game to look closer to modern World of Warcraft while still playing Wrath.

Dominos

Dominos replaces the main action bars. It gives you extra bars and lets you move, resize and rearrange them freely, with a config window to set them up. It is a good fit if you have more abilities than the default bars can hold, or you want your bars somewhere else on screen.

DragonUI and Dominos both change the action bars, so it usually makes sense to pick one of them rather than both.

Bags: AdiBags

AdiBags gathers your bags into one window and sorts your items into sections by category, so gear, consumables, quest items and trade goods each have their own place. If you spend time searching bag by bag for one item, it is worth a try.

Nameplates: NotPlater

NotPlater is a feature rich nameplate addon whose design is inspired by Plater. Nameplates are the bars above enemies’ heads, and a clearer set helps a lot in PvP and when tanking groups of enemies. On a PvP realm like Lasthavens, better nameplates make it easier to read a fight.

Raids

Grid2

Grid2 shows your party or raid as a compact grid of frames, which is the layout most healers prefer. It keeps a whole raid visible in a small part of the screen and is highly configurable. Healers should look at it first, and it helps raid leaders keep track of the group.

Method Raid Tools

Method Raid Tools (MRT) is a toolkit for running raids. It includes a raid note everyone in the group can see, tracking of raid cooldowns and battle resurrections, raid checks for things like buffs, and other tools for organised groups. It is aimed at raid leaders and officers, though anyone in a raid can use the note and cooldown tracking.

Loot: AtlasLoot

AtlasLoot shows the possible loot from bosses, so you can look up what drops where. It covers classic, The Burning Crusade and Wrath content, plus crafting and world events. It is the addon to open when you are planning which dungeon or raid to run for an upgrade.

Well-known addons that are not in the library

Some popular 3.3.5a addons are not available in the library, because their licenses don’t allow them to be shared this way. These include ElvUI, Details!, BigWigs, Bartender4, Omen and Postal. The library covers the same jobs for most of them: Skada for damage meters and threat, Deadly Boss Mods for boss timers, and DragonUI or Dominos for the interface and action bars.

Suggested starting sets

• Levelling: Questie, OmniCC, AdiBags.
• Dungeons and raids: Deadly Boss Mods, Skada, OmniCC, plus Grid2 if you heal.
• PvP: NotPlater, OmniCC, and WeakAuras or TellMeWhen for your key cooldowns.
• A new look: DragonUI on its own, or Dominos if you only want to change the bars.

Start small. Switch on two or three, play for a while, then add more. Fewer addons also means less to load on a phone or tablet.
