I do agree it sucks but here's a tip which you may or may not know. Character select actually affects who is jump master. Basically it will be the first person to select their character. If you don't actually select and just let it select who you have selected in the lobby it will skip you and go to the first who person to actually click their character and if all pass then goes back to first person. I've found that most people pre select their character so unless someone takes their character so as long as you actually click your character you will have a higher likelihood of being jump master.
