I struggle with each archetype "not being perfect" I am seriously OCD in games
Blasters. Say Ranged. Are designed as Blappers.
Corruptors. "As a corruptor, you might strike your foes down with blasts of fire, entomb them in ice, infect them with radiation, or curse them with pure darkness. As your foes are weakened, your scourge ability kicks in, increasing your damage to an enemy as their hit points drop" NOoooooooo Mostly buffers and Healers. Most heals buffs affecting anyone but yourself. Villain? From what Universe, lollipop love land?
Now, having said that I look at Marine on a Corruptor and I have to smile. This is a good debuff set. And the buffing it does is almost all also for the Villain Corr The Cone heal is a debuff. So, not too shabby. I can see a Villain using each of those powers and not being nitpicked by a morality GM for being helpful and heroic all the time. Most Corr secondaries fail that test laughably fast.
Water is not my thing, but this looks like a solid addition for Corr, which, as we know, is a very fine Archetype.
