Good game, might be hard for new players to get over the initial grinding of the early levels but after that it gets relatively easy.
Only thing i have a problem with is the finding friends system..... the problem is there is no system set up to find new players.
best suggestion i have is to put in a Que for people to find players willing to play with others in co-op or another mode. that way you can run into people and possibly become friends if both parties agree to it.
