Lol I figured id get an ein main and yeah genfus psuedo is good in the fact I barely sacrifice any damage lol. As far as ein goes I haven't really broken him down much I just do what I did in 4 lmao
He's similar to 4 with buffs in some areas and nerfs in others. The buffs were the bound system giving him PKK / KK and the changes to walls making it so that whiff punishment near them leads to guaranteed damage.
The nerfs were to his range game IMO. No 14i 6P+K or 13i 4K BUT 4K is a NH launcher now. So in a way that move was buffed and nerfed. Also SS being in the game hurts him a bit since alot of his best tools are linear.
