Every since 13.0.0 came out, I've noticed that the GSP cut-off threshold for access to Beginners Only arenas has been lowered! The bar used to be Elite Smash and now I float between having it accessible and inaccessible depending how well I'm doing in QuickPlay. This sucks for me because Beginners Only arenas are the only way I can play in arenas with strangers and have fun. On the plus side, it has gotten me to play characters I have with inflated GSP that doesn't reflect my skill level and just tank it.
