This is someone who's had a bad experience with one of these classes. Probably, sadly, under-geared against a battlemaster. The problem is and has been the battle of geared vs. un-geared and getting gear is really hard, frustrating and daunting. It takes weeks, maybe months, of playing every day because of the inane lottery system. Trust me, from personal experience, an ungeared marauder gets obliterated by a geared healer. Its true, you need skill to be really good, but simply having champion or, god forbid, battlemaster gear makes you a walking force of nature against anything that does not have similar gear.
