It doesn't matter if Americas and EMEA fans don't like it.
GE = India
XLG, DRG = China
Those two regions together, even though they don't interact much with us, are bigger than the Americas fanbase. For us it's boring, but, it increases their chances of making playoffs.
If we get an Americas vs EMEA 1v1 matchup, we'll probably end up with a dogshit team making playoffs purely because of luck. At best, we get GE in playoffs, who is decent.
Which is already a huge win for RIOT since it's the Indian team.
The Chinese teams will probably get stomped, but they'll still boost viewership.
