As a long term mmo player having played wow, rift, swtor, tera and war, I tried gw2 for the first time on sat. I had previously heard nothing about the game and had not bee following the beta. I must say I found the game refreshing to say the least.
The graphics are absolutely amazing, questing is very engaging and is never the same these are all great features, but in my opinion the best feature is the pvp.
Combat feels really fluid and skill full, if you dodge mobs or players attack it feels really rewarding. Wvwvw is some of the most entertaining pvp I've ever done.
I play a Mesmer and I have to say I'm I love with the profession it really is different from anything I've played before.
My advice to you is to ignore the trolls and fan boys and play the game to get your own opinion.
