I think it's the crappy map that is getting people down. If they had chosen a better one people wouldn't be moaning so much. The sector capture map is waaaaaaaayyyyyy better. But then I enjoy sector control (aka capture and keep the flag) much better.
I like to look at things more objectively and optimistically. The thing is, it's only a beta and already I'm enjoying it more than BFBC2. Even with all the little issues.
Ok, let me try and expand on what I like and dislike.
Like:
1) Hit detection that works: I can't remember once where I had opened up on someone only to not get a single hit while playing.
2) Gameplay: A mixture of BF and COD that they seem to be pulling off nicely.
3) Killstreak: They call it a chainstreak. You get a mortar strike after getting 50/100/etc points without dying. You get 10points for a kill, 5 extra if you headshot a him, 10 points extra for a knife kill and if you get payback on someone it's also 5 points extra. Last night I was trying to plant a bomb on one of the sites, guy was waiting for me and took me out, came round again and knifed him: Kill + Knife + Payback = 10+10+5 = 25
Halfway to my mortar killstreak. Planted bomb, blew up objective extra 30 points....... I has mortar combat.
Dislike:
1) Like Mappy said, Phantom bullets for teh suck!!! Hopefully it'll be sorted out with full release.
2) Killstreak/Chainstreak: Only 2 hours into playing did I realise that I was getting them!!!

There's no "In your face" notification that you've been awarded one. They need to fix that.
3) Very little recoil: Don't mind this too much but it would be best if they had a look at this.
4) The whole interface: Once you're used to CODs interface (Menu, Server searching, class creating etc etc) everything else is sub-par. But for MOH it's even worse. You have to press TAB when you're selecting you're class to change weapons, attachments etc.......... and yes, once again I only figured this out halfway through playing.

5) Sniping: It's about the only thing happening, but again I think the map plays a huge roll in that. For other maps it should be better. But I don't think it destroyed the game when I was playing. If you had a good sniper on your team then he would keep them busy long enough for you to sneak to the objective.
