I didn't originally like the Beta but gave it one last shot over the weekend (EU Beta) and went much further then my first play session. I have to admit that it does get more fun once you get around level 6 or so. The battles get a bit more hectic and the weapons (I played Marksman) get more fun to use. The game DOES remind of Diablo to a 'T'. I thought it was interesting to see the ravengers (-sp) jumping around in 3D after seeing them in Diablo 1 and 2 in 2D, it actually kind of freaked me out the first time one jumped at me, wasn't quite expecting that. I found the graphics to be great in some areas (underground tunnels looked good IMHO) and horrible in others, maybe they toned down the graphics in some areas (bigger open areas) to handle many peeps with many MoBs, not sure.
I may pick this game up to play co-op with my friends, just not enough co-op games anymore and this one looks like it would be a good frag fest with 4 other peeps. This game reminds me of a mixture of the Diablo series and Doom series where you can get some fast paced action with people in a co-op fashion.
Having said all this, I think the pricing model is HORRIBLE. Dev houses like ArenaNet have proven that you don't need to charge a subscription fee and then on top of that force customers to see ads regardless of how well they blend into the enviornment. So even if I and my peeps decide to buy and play this I will not support the subscription model.
Tough decision for sure, I can see this game being fun in a co-op mode but it's hard for me to support this greedy pricing model (even though I will keep the $10 in my pocket regardless) on the other hand. Decisions, decisions.
