Basically this, Stakers need even combat stats throughout. If you get 85 Def it could be a good Combat Staker. But you would be better of making it to a pure, zerker of some sort.
85 Atk at 1 def is a bad idea tbh adds a lot of combat levels, 1 def pures become extremly hard to pk with when you start facing, Zerkers and tanks. If you're going to turn into a pker of somesort you would have to get Chaotics a least to make up for the high attack level.
