More specifically, the Healer.
I find the healers move far too erratically to properly hit them. Also, they can perform some attacks without warning for too much damage (notably, their physical strikes with their wand).
They hurt just as much as a Thwacker. I find them overpowered to the point where they're suped-up versions of the Thwacker. They have almost just as many offensive abilities as healing - can they be nerfed a bit? Or at least nerf the amount of damage they can do.
Or is Tier 3 designed to have only 5* gear on?
EDIT: Doing Tier 3 runs with these equipped:
Bombastic Demo Suit
Heavy Demo Helm
Rock Jelly Shield
Dread Venom Striker
Prismatech Alchemer MK3 (I don't use this against Gremlins as it deals elemental damage)
Radiant Sun Shards
I agree! The problem is that even WITH 5* gear, you're still just as vulnerable to their blows as with 4* gear. :( It's the same with 5* weapons. It makes me very sad. :(
