Meta changing patch: NEW COMMANDER UPDATE - JUNE 14TH 2019
I think Jun19 new commander patch dont change meta too much for Ost win rates.
As your stats shown, as i monitor the top 10 ladder on this website.
Ost is worse faction, especially if you dont team up with an OKW player.
This SBP is good finally to give pio repairs, but i feel the main focus is to reduce OKW performance. I am not sure about it. The call-ins definitely affect the command panther which gets nerf along, while Sov who also rely more on Call-ins, get their KV and IS tanks a little more buffs.
