Who gets what buffs?

[Ferok]

If I'm the only healer, I give the main tank AC and give the puller SoW (if possible).

If I'm a supporting healer, or I otherwise have mana to spend, I'll give Strength, Dex to melee and SoW to everyone (again, if possible). Stamina to the tank/puller/necros is also a good idea, especially at higher levels.

Once regen becomes available, give that to the puller, the tank, and anyone else taking semi-regular damage. And Necros. They'll love you.

Once haste becomes available, give that to all the melee - no exceptions.
