We're barred from server first Turn 4 because..

do you have 2 warriors or something

We have one Warrior, but he can't tank Dreadnaughts because they can potentially one shot him if he gets bad RNG. He's in full Darklight, with Relic.
Even tanking the Knight + Soldier, he can still get a bad RNG chain and lose 80% of his health near instantly.

It's hard for healers to deal with it, because the damage he takes is inconsistent.
