I'd like to compile a list of the (self) buffs and (target) debuffs that are most important for each class and spec, in order to add a sensible default setup to my addon rather than making the user configure it from scratch after installing.
Specifically, I'm looking for raid buffs/debuffs each spec can provide, buffs/debuffs that are part of DPS/tanking spec rotations, DoTs or HoTs that each spec wants to keep refreshed (usually ignoring other people's versions of the same), etc.
As an example I've started with possible setups for feral druids and rogues, but I don't have enough experience with other classes or specs to know what they need to monitor in combat. I'll add others as they're posted; thanks for any contributions!
Some things (like Clearcasting) were intentionally left out, as I found that on my feral druid there's generally not enough time to see the proc and change which button your finger is already heading toward, while on my elemental shaman and mage I don't even care about it at all since it's up so much.
