2v2 map is sick, 3v3 is overall good, but one spawn is quite exposed. The 4v4 map tho... those 2 narrow ramps to leave the base are quite the concern, get a toss on the other team and they will FF you in until you get tech and army enough to be able to leave the base against a 4 player siege (and here I'm hoping your allies will help, because if they don't, the hard contain will be their death).
