I'm also really afraid than Asia start to dominate, and Val start to die in occident buuuut, I do think for the moment EMEA is pretty safe, for 2 reason, if I tank Premier Data, EU and TR are both winning player in term of percent, EU went to 24% to 24.5 while TR went from 3% to 6% wish is impressive, we also have to keep in mind that Ukraine war will end some day and a lot of RU player that are currently in APAC will play in EMEA and we will see a lot of great Russian team, we also have Africa that will deelop some day. I'm not worry for BR that got a sligt increase and LAS/LAN seems kinda okay and are stable.
I'm worry for NA, really worry for NA's future, in 2023 NA's premier team where representing 22% of the premier team, now they represent... 14%, every split, they loose 1%, and it seems they are about to stabilize at 13% for the 2025 year, this is really really not good, and thats wone of the reason why splitting AMER in 2 might kill the region, more you have T1 team to scrim against, more you improve, and the bad year result of NA could be because of BR 2025 crisis. To make things worse, NA doesnt invest into aca team, while a team like T1 litterrally get saved by an academic player
Now lets look at APAC, KR went to 8% to 12% of Premier team (They even got a peak at 22% after T1 win), India went to 4% to 5% (And even 7% in the most recent split), Oceania is in crisis because no T1 team (From 2.6% to 1.8%), Japan went from 8% to 2%, Asia where dying they went to 11% to 9% (But boom at 14% right after PRX win), so I think what is making a region strong is the density of good T1 team in this region, 6 SEA team and 6 EA team allow everyone to improve at the speed of light and start to dominate international event. As you can see they are a snowball effect, when a region win an event, more people come.
In this Asia and Pacific have to be split in 2 at some point, because they represent 40% of premier team versus 30% for EMEA and APAC, Because if the trend of winning continue it will bring even more people, by putting them into 2 place that cant scrim each other, you reduce the density of the 2 region and make both weaker, this will allow unrepresented market to finaly have a T1 team, Vietnam, Oceania, and even maybe Mongolia and MENA could finally have their T1 team (If Riot split APAC, giving Asia MENA could balance things out plus allow them to have a spot since EMEA is saturated), the only mean to make the playerbase grow is to give them outlet, and without T1 team they dont really have outlet. (They are technically also the question of Russia, and where to put them if EU and Russia have geopolitical problem, plus the problem of Russian playing in EMEA Tokyo that need to be solve at some point).
So ; tldr I'm not that afraid, EMEA have future, BR is okay, but i'm afraid for NA, they have a risk APAC continue to grow, but in that case the only solution is to split Asia (SEA+IN+MENA ?) and Pacific (KR+JP+OCE) to stop the snowball
note : all of my data are without counting China, start is 2023, and current data are 2025
