that's actually a good point mr aim
when rgl put such heavy class restrictions in advanced, they basically ensured that the teams that won it would be a) super hungry to go to invite because they're not sandbaggers, and b) even more likely than usual to be bottomfeeders in invite because they essentially can't have any mainclassers with invite experience unless they joined the team in the offseason
so those teams need to actually be allowed to play invite or else theyre stuck in purgatory, either that or advanced, ironically, needs a sandbagging team or two to keep them from being in this position in the first place
