If your dps is still on par with decent it doesn't matter. If you can keep up with everyone and not die all the time it doesn't matter. It may be rude yes, but if it doesn't effect me or the party I simply don't care. When you end up carrying someone because they think they can switch to all white gear and still be ok, it is not ok. I have left parties as a whm before when I have run into messy WP's or Ak's, if no one is SB and we are messy, meh it happens, but if I'm wiping over and over because the dps or tanks are SB everything yeah I'm gonna leave. I will tell them why to, not like they care, if you are rude enough to pull that shit, you wont care if the whm is yelling at you for being a idiot.
