Not a fan of the mass resist SLA. Will be very good in heroics to get that at level 12 for the heroic TR crowd but for epics, seems mostly meh. If you really need say, fire resist when playing at cap, you'll be wearing an item that is greater than 35 that will override/won't stack with the resist. I really was hoping for Heal considering Beacon tree has it and iirc part of the reason as stated in a dev post was an attempt at parity with that tree.
As far as Martyrdom, just add it for free to one of the cores if you want it to be a thing for flavor. I think it is kinda cool from a flavor perspective. But practically, it's still not worth taking for anyone even for 1 AP that gives what 3 AP did before. An ability that only works on death is kinda cool thematically but not useful practically.
Disappointed that some abilities like radiant burst, divine healing and bliss weren't given some buffs other than AP reductions. I know this is intended to be a quick pass but does tweaking these numbers up a bit really require a lot of dev time?
Melee cleric enthusiasts like myself would really love a burst buff as we can get more use out of it than caster clerics, being near the melees more often and all. The healing we get out of it feels lacking.
Overall the AP reduction to many abilities in this pass was nice, but playing with the new tree on Lamannia I felt forced to take weak abilities just to get up to what I want in the higher tiers. Because the lower tier stuff in the tree is now cheaper, but remains weak.
Last thing and fairly minor but as I mentioned before Radiance needs a name change. Radiance already is the term for light spellpower boosts/light damage found on equipment. This is a defensive CC elimination spell so it's just confusing. I can come up with a bunch of potential new names if the devs want suggestions.
