Well, I currently play WoW, although I hate myself for it. I picked up EQ2 and DoF not long ago, but I just couldn't get into it because I couldn't find a class that was perfect for me. WoW appealed to me, if for no other reason than that a Warrior could actively switch between being a tank and a DPS beast, even mid-fight if they wanted. But the level of detail, immersion, and effort developer-side that EQ2 has just blows everything else out of the water. I really wish I could get into it, but I'd rather not waste ~$20 on something that I'm just going to put down again for WoW. So I want to make absolutely sure I've found a class I want to go before I come back, if at all.
I got 4 characters to Lv12 (Predator, Pre-Berserker, Bard and Mage) and I was actually really dissapointed when I couldn't get 'hooked' like I semi-did with WoW. Style plays a huge role for me in MMOs. I like being able to be a complete showoff, and a bit of an *** in my fights (I was a Stalker in Ragnarok. What more do you need to know? Completely removing a Knight's entire set of equipment and just standing there as they try to hit me is the funnest thing I've ever experienced in an MMO), so if you've got any ideas, please, let me know. I guess a movie of a few classes fighting would be nice, so if anyone's got a link that'd kick some serious ***.
