I don't know, I use death at the top level completely maxed and overall I like where he's at. He can come in clutch at the right times.
I'm not saying he couldn't be better obviously, but he feels balanced to me.
Plague though, that's a different story completely. No one fears that guy. Kinda sad.
If I see Plague or War on defense I breathe a sigh of relief, but if I see Death or Famine i'm on pins and needles.
Not because they're op of course, but because of the unpredictability.
