Always nice to see someone ask to remove one of the things you enjoy most about your class.
Being able to directly assist allies besides just keeping them alive should be more common (and not through indirect crap like "nearby allies gain X crit" from soulbinds).
Maybe the problem is not with the ability, but with you taking part in a climate/culture that supports paying for buffs. I play with a group of not morons who know I will buff whatever gets us the highest net gain in DPS.
My list:
1. Removal of borrowed power systems that last for a single expansion.
2. Pet Battle events no longer prevent other events from taking place (weekly bonus events).
3. Tank spec for shamans that focusses on Earth abilities. (uses shield and mace obviously).
4. Discipline back to a spec that isn't a gutted. It feels really bad to spend over half the time doing a dps rotation and still fall behind Paladins, Shamans and druids in DPS. Just put us back to the old shielding spec since we're OP pre-shielders anyways, just with a stupid 1 min rotation of homework that's harder to balance.
5. Reputations account wide.
