They are testing it to prevent any bug. Imagine for example a bug abuse to create infinite tbl points, it would be catastrophic for our economy. Testing is a boring (imo) but important thing to do before you release any feature, I can’t blame them for that. We need a stable PvP.
Edit : Nevermind, I read too fast your post. Well if you look in-game you will see that 3v3 is already implemented with the patch we had 2 weeks ago. I guess they got the patch like that and can’t change the sequence. 2v2 has been removed so we have no choice but to wait
