It's not a xenophobic problem, it's more the fact everyone was is still traumatized by TGRD affair, that left a mark in people mind and especially usian mind "if even TGRD isn't allowed in franchising, then so many structures can't do the cut". So if a structure that come from NOWHERE just win ascention they assume they have litterally no chance because TGRD precedent.
2G ascending may be the best thing ever for Riot, it will prove to everyone that anyone can ascend, not only big clouted team that come from very rich country like USA, SG, FR, it may even attire a lot of small/middle structure into tier 2, it will just prove you can qual even if you are not a huge name
