Hi, im leveling my caster TR as clonk currently, and am using divine disciple lvl 5 atm. Of course I also use radiant servant for the burst, but on the long run, whats better as tier 5 enhancements?
Flame Strike SLA (longish cooldown, takes a while to come down, probably low damage late on, but still an aoe damage SLA)
+1 evo DCs
+1 caster/max caster level (but not for blade barrier)
-most points to get up to 30 are well spent in this tree, but no spellpower per point in tree
-core abilities after +2 all saves are pretty useless imho
Reactive Heal (havent tried it yet, sounds nice)
Cure focus (sounds meh, as a splash in GMoF I wouldnt gain too much)
-most abilities in the tree arent too interesting, but you get 0.5 spellpower + 1 healing spellpower per point spent so they arent totally wasted.
-you want 20 points here anyway for regenerating bursts
-improved empower healing isnt really worth for me since i dont carry empower healing. Maybe for the crit chance.
For me, it comes mainly down to the decision aura vs flame strike +1 evo DCs.. still using flame strike but tending towards aura for endgame.
