Today map standard for 2v2, correct me if I am wrong, is easy 1 expo and then hard to get expo's mostly, so 1 player (the zerg most of the time) gets to have an expo before you all in the crap out of the other team cause you can't have decent macro in such maps.
What I suggest is people trying to find ways to make 2v2 games better and longer, maps that you can FE with ease if you know the metagame for 2v2 (I don't play almost any 2v2 even though I like the matchup, so I don;t know the metagame sadly). If people want to get 2v2 to have big tournaments and stuff, there needs to be maps first.
Late-game 2v2 can be REALLY good to watch, it has so much more options then 1v1 it is just great to spectate (even though it is harder to play for sure). If you want a few examples I can think of right now, imagine this:
Late-game TP vs ZP, after all the mid-game pushes everyone is even and the Protoss wants to go for a transition into to the rarely seen carriers, normally in 1v1 it would be VERY hard since he will have a vulnerable time, but here the Terran can harass and force the enemies to stay in base and so we see things we would not see in normal games.
I can think of other much more exiting things that could never exist in 1v1, and make the game much better to watch, but sadly these things will very rarely if not never exist in today's 2v2 since the maps wont allow for macro games and are just more favorite to 1-2 base play, which is pretty sad.
I myself am not a good map maker, while I will try to make a good 2v2 map I will most likely wont succeed. And so, I ask you, the great map makers of TL to try and balance at least a bit the game for 2v2 macro play, if there will be some good maps I am sure people will try to make tournaments with these maps and the community will better recognize the 2v2 matchup as the great thing that it is!
I call in for the community to make good, macro oriented 2v2 maps, in order that we will not miss the awesome potential that lies in the matchup.
