I wasn't too impressed after playing two matches. Typical camp fest with the Rush game mode.
These controls feel unresponsive as hell. I had a fucking great time setting stuff in the menus(mouse constantly disappearing). And WTF WE HAVE TO LAUNCH THROUGH ORIGIN, AND THEN THROUGH A WEBSITE?!
WTF
Really? I don't have the beta (not pre-ordering and probably won't even get this since it's not on Steam) but from what I played of the alpha the controls felt responsive to me. And they got rid of the floaty feel that BC2 had.
I think Battlelog is great, it's a vast improvement over BC2's laggy UI. Not happy with it requiring Origin though, just yesterday it started maxing out my CPU for no reason.
It's in Open Beta right now so you don't have to pre-order anything luckily although you do still have to use Origin....
