Easily the best Pocket who is looking for a team in open and my long time friend, never seen any instability in our friendship, and I honestly think any criticism of him saying he is unstable is very overblown. He was an absolute angel when he had to take over for me at the end of S18, and was a direct upgrade for the team, none of them had any problems with him, and I don't see why you wouldn't at least give him a try.
Or you could listen to someone who isn't willing to overlook a night of scrims that was probably very stressful (and painful seeing as his arm was fucked up) and feels the need to bump the guys looking thread over it instead of attempting to talk to the guy.
