imagine playing a demo and you get into lobby with prot palas and you face ,feral , sub and dh
rogue just duels you every go = insta lose , while as lock you just sit and watch yourself lose, because you basically play without a healer that can trade cds to keep you up
either ban tanks for solo shufffe or make every class have some sort of giga def cd to counter rogue duel, cause playing that lobby was the most miserable i ever felt in a long time
