2v2 is bugged or something

After ranking fresh accounts to master tier 1 in 2v2 over 20 times there’s something i’ve noticed.

The moment you get promoted to master tier 1 the match making goes to complete dog poop.

The last three matches after this Tier 1 master promotion has netted me a total of 0 MMR and 3 division points.

Your system is broken please fix the match making for 2v2.

Thanks
