No Longer works, got 2k in 2v2 and cant buy it!
No Longer works
Many people missing the point. It was a one-time thing that's hardly going to be repeatable. If during that time you had 2k+, you'd get 2K+ achievement for the previous season. That doesn't mean getting 2K now will also get you it. Yes, you can't get it anymore - No, that does not mean it is fixed per say.

Yeah I've gotten mine that day. I can confirm it is not 2s only like someone said since I was doing 3s only.
I get previous achiev, from 2k RBG in this season
