I think I've had enough of this one, have put in 20 hours, got to level 40-something and have a good k/d ratio of 2.7 but still find it very frustrating in parts and for every good game you have to endure 2-3 one-sided/campfest games. Other things that annoy me are:
Graphics are too messy, making it very hard to see someone until they move, hence any larger maps are far too prone to snipers/campers.
Weapons are not balanced, 90% of people are using the submachine guns since the rifles are useless without stopping power unless you are playing HC.
Hit detection seems to be very off compared with COD4 (or the net code isn't up to scratch).
War mode is rubbish, have only played one game that ended properly, all others go to "final fight" and come down to a lucky grenade that takes out 3-4 people and leaves the flag open.
Dogs are far far too powerful and in HC are a joke (one bite to die), the helicopter in COD4 was very powerful but at least you could get rid of it. To make things worse, the dogs lead the other team straight to you, generally leading to someone else getting 5/7 kills.
Tanks are far too hard to take down, getting one is pretty much a guaranteed 5+ kill streak on most maps.
Most of the maps are pretty average, there were only a couple in COD4 I didn't like and a lot of them I really liked, in this game there are none that I really enjoy as they all seem to encourage you to camp with some claymores, sorry I mean bouncing betties
I find the voice overs irritating other than the Americans, verging on racist but I guess that's about par for the course in a World War II game.
There are some parts I like (single player was a laugh) but in general it just feels like an average mod of COD4. I'll be going for a mix of GoW2 and Left 4 Dead instead, the latter also seems to have less idiots than you get on WaW.
