We do 1v1's, .. Why not 2v2's?

I've been seeing a lot of 1v1's lately and I think they're awesome.

I definitely understand the fact that 1v1's are a good way to compare one player's skill against another.

I was actually watching a 1v1 of Bjergsen vs Doublelift on YouTube and of course Doublelift got stomped by Bjergsen because it's an ADC vs a Midlaner (and Bjerg is just better).

But this gave me the idea of having a 2v2 match with a typical carry/support combo.

Could be fun.

I am wondering what people think would be best for the rules on it.

Same as 1v1? First blood, first tower, 100 cs, .. ?
