I'm enjoying the beta, sort of...
It's certainly got it's fair share of problems (clunky menus, ho-hum visuals and a high chance of spawn camping) but overall the gameplay feels solid and I haven't experienced any major signs of lag yet. I played a few hours of it with a buddy yesterday evening and was having fun so thats the main thing to look for in a game I suppose
With regards to the visuals, I am assuming the beta we are playing is an old build and Danger Close/EA are mainly using the next week or so to test server load and highlight any bugs that may have been missed.
Overall, hardly a day one purchase but I may check out the finished product sometime next year after a price drop.
