I need to learn more about what other classes can do and really need to know these things for pvp :P
if anyone can post a site or tell me how i can learn these things without making a char and leveling it to 80 with every class i would be very happy face
Will it show all or do i have to search?
Here's an example for finding abilities for a class in wowhead;
Search for: Paladin
In teh drop-down menu that appears while you type, click the "paladin" class selection. In the window that loads, go to Abilities.
Might be a less convoluted way, I just poked in there right now and found that method quickly.
Here ya go, not sure if this will help out, but a cool little chart I picked up a long time ago about Buff stacking and stuff.
Edit: Oh, and a note, this is obviously not updated for 4.0... lol so probably irrevelant info to your question.
