Just letting everyone know that this PTR update has been pushed to the main game. Patch notes are here: https://us.battle.net/forums/en/overwat ... 0758787028
The only changes between the two are some competitive mode ranking changes (such as better placement rankings, shorter seasons and more comp points) and a shit ton of bug fixes.
From experience I can say that DM and TDM are incredibly fun to play around in. TDM is 4v4 which leads to different team comps being made and DM is just a fun fuck around mode. The new map is pretty sick as well.
This update however does NOT contain the more recent PTR changes
(Junkertown, D.Va changes and the changes that made Mercy OP as fuck). Those will probably be coming later as they are more heavy changes and are actually getting changes as we speak.
