Well, as expected there are definite pros and cons to it. I'd still prefer to see more classically defined roles (tank/healer/rogue/wizard) with their own spell and skill sets as opposed to them being predicated on weapons. Too much time spent reviving people, pets and npcs.
I played a ranger up to 20 and quite enjoyed him, although pets are pretty useless atm. I did get me a pet shark for aquatic stuff which I loved. It's definitely a huge, interesting and beautiful world. I spent a lot of time just running around exploring stuff. Also started a human mesmer for the last few hours of beta and it was fun.
Crafting was a mixed bag. Not great, not bad, needs work. And too many pf the mats are way too hard to come by. They definitely need to be upped. I wish all CRPG/MMOs would take a page from EQ2/Vanguard crafting.
All in all I enjoyed it quite a bit. It still needs a lot more time in the oven at this point. It being F2P at launch is a smart move because it's definitely one of those games you'll want to hop in and out of in stints.
