This is where we can all post anything and everything about add ons. Any questions about them, which ones you use, what they do. So to start things off i'm goin to post which ones i use and what they do,
Atlas - Instance map browser, also comes with a few other add ons all in one. Shows you maps of almost all instances and things, also shows you what drops from what monsters and bosses on normal and heroic modes.
Skada- Shows you your dps and other things such as groups dps, how many swings you took, how many misses and all kinds of things. Theres alot of options you can do, and ways to customize what the bar or display box looks like.
QuestHelper- Almost all people know this one, but for you's that dont, this add on shows you on your map where to go and displays and keeps track of what to do on quests. I think this add on is very useful mixed with the next add on on the list i use.
Where to Now? - This add on i think is pretty cool, what it does is shows you and gives you a idea of say 5 places at your level you should or could be leveling. Its cool it shows you like 5 places and shows the level range the place is so you can figure out where your goin to quest next and how long your goin to quest there. It also gives you a list of 4 or 5 instances again you should or could be doin.
Deadly Boss Mods or DBM - is a very handy one anyone who is or is goin to raid should have.
Well those are the ones i'm useing as of now so lets hear what everyone else is usein so maybe we all may benifit from some info.
