We all use some addons to a greater or lesser extent, so i thought a list would be handy ^_^ (work in progress)
Where to get them – These 2 sites only host addons that are endorsed by blizzard, other sites host other addons that may be classed as bots or scripts, and compromise your account. (obviously the dbm and warcraft logs sites are safe).
Raiding addons –
DBM or BigWigs – does it all,warns of incoming abilities, shows raid cooldowns etc.
GTFO (handy for other situations too) – warns you to step out of bad.
Exorsus raid tools – similar to dbm etc but more detailed and extremely useful for mythic raiding.
RSC -, tells you if your group is missing buffs, food, flasks, runes etc.
Raid assist – used to be Iskar assist, does lots of useful stuff.
Thogar assist – shows where the trains are coming from next.
Weak Auras 2 – a powerful and flexible framework that allows you to display highly customizable graphics on your screen to indicate buffs, debuffs, and a whole host of similar types of information.
TellMeWhen – provides visual, auditory, and textual notifications about cooldowns, buffs, and pretty much every other element of combat.
Pawn – tells you if a piece of gear is an upgrade for you or not. Bear in mind sometimes its default stat weights aren’t correct. Find better ones from – icy veins, your class discord, or by simming yourself.
Details! – gives much more info than skada/recount, shows graphs and charts etc if thats your thing, can be set to announce interrupts, firt hit, deaths etc, and you can have as many windows up as you want.
Skada – uses less resources than recount and you can have multiple windows open at once.
Recount – basic and is known to use lots of resources, can cause lag in particle heavy situations (think kazzak)
Healer addons –
Clique – You have mouseover macros, Clique lets you react faster and make infinitely better use of a ton of your abilities.
Healbot – meant to aid with healing, but i’ve heard many healer swear off it for vuhdo and decursive.
Decursive – cleansing mod intended to make affliction removal easy, effective and fun for all the classes having this ability.
Vuhdo – this is about displaying the health of raid members in form of clearly arranged bars. VuhDo is primarily directed to healing classes, but will make use to almost any other class. Moreover several healing spells or other actions can be asserted to mouse clicks on those bars (Click-Heal).
Healium – provides a customizable and intuitive interface optimized to make it easy to heal.
Tanking addons –
Parrot or Mik’s Scrolling Battle Text – highly customisable addons for displaying floating battle text while in combat (incoming heals, damage of your spells, etc.). They both work very well by default.
