The only way you could stay on M25 at this point is if you glitch. If you don't, you're almost guaranteed regular losses to vastly inferior opponents.

I played M23 up until 3 months ago, I had a blast. There was only a handful of glitchers left. I would still be playing but there was only a couple players left towards the end. One was a glitcher and I couldn't beat him. The other wasn't and we had good games. It was time to move on. I'm having fun in M25.
