A dead monk is worse than a monk doing 5% less damage, of course.

If you have lots of trouble dodging stuff, you can and should use Fists of Wind for the time being, while you grow accostumed to the fight to the point you can use Fists of Fire, while perhaps using MrDiezel's macro inbetween, once you kinda know what to expect. Of course, that would mean your gear should be very good to allow you to still put your weight even with the wrong stance.
