The only people that whines about class stackings are mostly the one that are terrible at the class they played so people never let them go, face the fact, you are terrible and SE is not going fix it.

Most endgame LS has zero issue trying out different setup and wins, accomplishing things and having fun at the same time, yes the issue isn't with the elitist, it's with this terrible players that are hiding behind casual cover.

It's a common known fact, most melee DPSer especially have zero freaking knowledge about enemy moves, timing their WS and get the way out of shit like Scorpion Sting, where to run when Chimera does certain breathe, etc etc.
