I played 3 antag games last night. Lost 2 (Low Blow with a 11% MMR handicap, hardly any AI resistance and I got steamrolled, and In Medias Res, scored 50 kills but just couldn't finish the job), won the last game on HBaT ending RIGHT before the reactor hit 90%.
So far, I'm not feeling like I'm getting a lot of help from AI. My MMR just dipped below 50% as of these losses, and the last 2 or 3 antag games I played I lost due to huge MMR differences, I was up around 56% and kept playing games 12-19% lower than me.
I CAN say that I got games much faster than usual, since the patch! So that's nice to not wait for 30-60 minutes to play a game!
