Hi. First, no way you’re 190 playing JUST Pred, unless you have less of a life than you’re saying others do. Secondly, Katana doesn’t need a buff; use a stronger melee class. And stop using the base war club, use the new Hook. Thirdly, Preds are not 90% melee. I only attack with melee when I know they’re stupid, and I use Valk/Axe/Fearless 100% of the time. If I jump in and get lit up, I know I need to switch to caster and wear them down. Its not a hard concept to grasp. Sounds like you just had two bad matches and now you’re complaining. Git gud.
Lastly, chill out. Its a game. Stop insulting people, it does nothing good for you.
