Imo it would be cool if we had 1 spot for eu 1 for cis and 1 for tr.
Then place 2-5 from eu and 2-3 from cis/tr meet in a 8 team tournament where 2 more teams can qualify. It gives cis and tr a guaranteed spot (wich I think everyone would like) but also rewards the best region out of these 3 and keeps up the competition between the 3 regions.
This system would delete most of the contra rguments for EMEA and for splitted regional slots
