At first I thought you were spot on, but since this is for a hit 3, at max 2LB with troops we are looking at 2400 burn all in over 4 turns. Thats 1080 in boosted hp for the entire squad.
Would I bring him in as a main healer? Absolutely not. But he is going to hit much harder than aramis, take some buffs away for 4 turns, heal while applying the burn like an STD from hell, and has a chance to steal a random dispellable buff with shared damage to allies, keeping him alive that much longer.
Had none so pretty happy. Plus our alliance runs red tank so Sparklight will get ascended once I get that Damascus blade. Starwalker not so much, as I lack Telescopes.
