My solution wasn't "play a shitty class" it was "do extra stuff out of game until it's difficult for you. " lets face it, you could even make LFR a challenging hell for yourself if you really are interested in diffculty using that method.You also seem stuck in willful ignorance. Every single post I've said I want better class balance, and that I enjoy difficult fights. The answer to this is not, has never been, and never will be "play a shitty class" -- so stop repeating it please, you're making a fool out of yourself.
peel an orange and do lfr while also completing a rubiks cube. Hurrah, you are doing something difficult and no one else needs to have nightmares in normal mode again. Everyone wins.
