Divine Disciple = 81 ap
Radiant Servant = 85 ap!
To put the above into perspective Warpriest is 64 ap!
Now Divine Disciple is also too expensive but the real issue is that a good 40 points in Radiant Servant is required by ANY Pure Cleric and by a large number of Multiclassed builds too {those with only small splashes}!
This makes Divine Disciple basically unplayable!
It also hurts Warpriests even with their smaller tree as that tree is mainly defensive and most Warpriests will be multiclassed for offensive melee options!
Oh and of course - Nothing in the top tier of Warpriest or Divine Disciple comes anywhere near to matching Radiant Aura!!!
Now obviously I'm not suggesting any nerf to Radiant Aura OR the removal of said Enhancement - Either of which would make me very angry indeed!
So:
1) Remove the fluff {Divine Cleansing, Bliss, Purge Dark Magics, Divine Healing, Martyrdom} from Radiant Servant and replace some of it with actually useful abilities!
2) Divine Health is Tier what now? This needs to be placed lower in the tree to make it worth taking!
3) Reduce the ap cost of the tree as a whole to no more than 70! This goes for Divine Disciple and any other Class trees that currently cost more than that too!
4) Move Radiant Aura to Core 4!
5) Triple the benefits of Improved Turning so as to help make TU more viable in high end content
6) Who uses Pacifism EVER? It's a pointless AP sink and a required Core! Get rid of it and move the current Core 4 {Imp Empower} to Core 2 so as to make room for Radiant Aura at Core 4!
I'm sure others can come up with better ideas for Divine Disciple than I can - I honestly don't even bother with that tree as if I wanted to play a Shiradi Caster I'd be playing an Arcane
It would be nice to be able to buff up my CCs and Instakills but Divine Disciple is too heavily biased towards supposed DPS Spells that aren't even worth memorizing!
