These are some pretty sensible ideas. To be honest, i dont think a healing potency increase shouldn't be tied to either stances, as i really dont see any reason why our spells can not have the same healing potency as WHM/SCH in the first place. The ability to switch sects in fight is something that may have originally been intended for AST, as we were told it was on a long cooldown so we would need to master when to switch; bringing this back in would be welcome.

Benefic 2 proc, yes, but maybe not 50% of the cost, maybe reduced to 75%. The reason for this is that the more experience i am getting with the class, the more i am realising how powerful it is to move and cast instant heals, the slight reduction in the cost kind of offsets this power (like sch power to move and heal comes with having to decided on what to do with the 3 stacks of aetherflow over the next min, closest analogy i can think of).

Collective unconcious, i really just think we should be able to chanel this initially, then leave and the bubble stays up, having to stay on the spot for its duration or lose it is unwieldy in raid content. So what you are saying bu minus the duration cost if you move .

Cards, yep they all need 2 "modes". Helps make their situation use slightly more palatable. Although ewer and spire do need a little reworking as well. MP and TP refresh maybe?
