My biggest frustration is the decision to make non-solo healing a black box this expansion. We know what goes in (potency, crit bonus, ab mod) and what comes out (massively reduced healing) but we have no idea how they're related.
We've been told that the 'reduction' is applied to healing received, on the target of the heals, not healing out, on the healer.
The biggest proof we've got that 'reduction' is not uniform is the significant difference in the size of the 'reduction' of different heals.
In T1 zones, I've recorded some heals being reduced by 74%, others by 59% and yet others by 0%. These numbers are... highly suggestive.. that the healing reduction is done, literally, art by art. That suggests that devs could decided that heal A belonging to class B is 'too strong' and could adjust it to do whatever they want it to do... without any indication to players that a change has been made until the heal fails to perform as it has in the past.
For people who are 'pushing' their toons, this game is a numbers game.. for healing as well as dps. Unfortunately, it appears that the devs have decided that healers should be denied useful information about how their heals actually perform.
To make things more 'fun' quite a few mobs do % based damage to players... so as players get more hitpoints.. healing DOESN'T GET EASIER....
So healers should always have to work hard, even if the content is trivial... because reasons
