I recently went from 2 TC20s down to 1 for the same reason. Leveling Rigard, Poseidon, Boril, and Caedmon all at the same time. (No red projects at the moment, sadly, so reds are also going to the very hungry Poseidon.) Since all their specials are at 8/8, I can use whatever pops out of my TC2 or TC19 immediately, without worrying about roster space. It’s pretty sweet.
HP/def all the way. Healers gotta heal, and they gotta be alive to heal. His tile damage is just a nice bonus. He’s in my blue titan stack because of his tile damage (so is Skittles, btw, and for the same reason), even though I never need a heal against titans because I have a very small alliance. Don’t discount that dispel, either. I actually run three dispellers (Melendor, Sabina, and Sonya) on my main raid team. When somebody like Wu or BT fires, you gotta be able to counteract that stuff pronto.
