It also doesn't help that Samurai is one of only two 2H Melee DPS, too and from what I've heard, DRG is usually looked down upon because it was once the "people trying to be cool" class, and there were a lot of bad DRGs which gave them all a bad name, and what little I've heard about their rotation, it sounds like it isn't anywhere near as fun.

So if you want to be a 2H melee, SAM is pretty much where it's at.
