4v4 Execution is imo, the way Gears was intended to be played. I'm not opposed to Warzonne being added to Alpha at all, though. Reason being is that if you down someone from far away in Warzone, you can kill them. In other words there can be a team that wins with no CQC at all. Not that this is the worst thing ever, but in execution if you want to earn your kill, you're gonna have to get your hands dirty. It also causes risk, do I want to leave my position to go get this kill or what? And then that's tactics.
Oh, and I loved Mausoleum, it wasn't a top Gears 1 map but it's better than a quite a few of these maps in Gears 2 and Gears 3.
