Yeah,... how about no.
My DH is there only as an alt.
As long i don't play it in any content that really matters (I basicaly only do invasions on him) i'll use whatever looks the coolest... it's not like i need the extra dps off optimizing my rotation, which is rather boring at level 100.
In short: I play this class to waste time -> doing a suboptimal rotation wastes more time per mob -> profit
If how others play a class casualy "hurts your eyes" so much i'd suggest you play in less populated zones, or try a single-player game.
