I played it...the learning curve isn't that steep, there just aren't any good tutorials. Some guys on youtube though have pretty much taken the time to walk through every aspect of the game. (the developers made their own youtube tutorial but it's rubbish.)
The problem I have with this game is, unless you pay money, it takes FOREVER to get enough cert points to afford any substantial upgrades for your characters. I stopped playing after a week and went back to bf3.
The sheer scale and chaos of the combat is great fun though.
