This game looks pretty sweet. I'm still a Private, 1st Class, but it's definitely a lot of fun. It's the kind of game I wish came out after finals (having my three hardest exams in a 26 hour span is not my idea of higher learning... more like some kind of endurance test).
I've been trying out the different weapons, seeing what I like and all that. So far, my favorite is probably the BS/Sword combo, with the two rifles from the training in case I can sit back and shoot. I'd like to get one of the energy shields and a particle sword... they look fun.
Gear is certainly a major factor... that WoW comparison might be a bit exaggerated, but it's not too far from the truth. Whereas I can shoot and dodge for a bit, they are able to fly around like some kind of retarded seagull before swooping in and skewering me. It's amazing how much some people have played the game already... I've barely had time to download and get into it.
