The problem with this is the same as with the covenants. The community's mindset. The idea is cool and all, but the result is the opposite they want to achieve. People won't feel rewarded when they have this buff, they will feel punished when they don't.
Even ignoring the stupidity of stuff tied to covenants when swapping covenants won't be something easily doable, can we talk about how annoying it is that this is a buff tied to AOE damage/healing around yourself? As a guy playing a Kyrian priest on beta, in order to even use this buff, I have to chain myself to staying in melee range as much as possible. Why can't it be "your abilities fire anima at the target, which explodes and deals AOE damage around the target"?
Lol all these people mad because they dont have a guild to run with XD
