Well, I just got my beta key a couple days ago and been giving BF:H a good trial. A few things I noticed I think they need to get better with. The 4 soldiers only that can be created, that sucks, all 6 classes should be available. Being able to select your own server(any game online should be like this) is something they should include. Naming your soldiers I think is very stupid, your screen name you have the EA account with should be your soldier name(like mine is "msdz" through EA but it was not able to be used on any soldier), that way when you are playing against people they may actually know who you are, not 4 different people.
Also, I think it would have been nice to select different soldier classes without leaving the game, depending on the map I don't always want to use the same class of soldier. So instead you need to leave the game then change you soldier and then hope you get back into that map again(seems like when I try this I go to the map I don't want that class for again).

The game IMO is fun, took me a little while to understand how to set up my soldier with the abilities and the buying of weapons(no money needed for this). Oh one last thing, from the forums this is apparently another issue still, you lose connection quite a bit. It is not really bad for me but for some it seems to be a real pain. It always seems like I lose connection when I am right on the verge of getting all the requirements for the one badge(can't remember the name of it). For a "free game I guess they kept it pretty simple and tried to keep it fun. I guess I was expecting to much. Still fun it is not something you may want to play all the time.
