i have played rift in the past, when it first came out, and i can say from personal experience it is an amazing game. i quit WoW after 3 years of it for Rift. that being said, im not playing at the moment but in May when i start going to college i plan on getting back into it. i know i am new to WN but i would really love to get a WN guild going in Rift.
i personally prefer defiant, and pvp servers not for direct pvp, but the random world pvp encounters that take place when you least expect it. im not a pvper per se, but i do enjoy battling it out with a rivaling faction member when you cross paths in the wilderness. and by that i dont mean ganking. ganking sucks but its a small price to pay for the thrill of world pvp.
anywho, i think Rift would be a great addition to the already vast selection of games
