It's really easy to get steamrolled as Allies especially since it seems like they're always outnumbered. And playing as Allies is really challenging but it makes it that much sweeter to win. On Axis it's also pretty fun to be in the bunkers with a rifle and just pick off the Allied soldiers after they cross the berm. As an Ally it can be hard to get off the beach and when you can get across the berm you're almost to safety (relatively speaking) and it's soooooo frustrating to get nailed there. It's equally gratifying to being causing the frustration as well.
Avalanche, Donner, Palermo, Santos, Hobofire, Caen, Jagd are my favs!! There's another I'm forgetting the name to, there's a bridge in the middle with a 2-person cap at a tank, and one 1st flag on each side, small map but I LOVE it!!!!
