Riot has to chose:
Either financially support the leagues if you want them to remain split
Or allow leagues that are struggling financially to merge and allow for better sponsors (due to higher viewership), more orgs, more competition and less organization overhead
when looking at it competitively the system is completely illogical too since the only way into t1 has restrictive rules that don't apply to t1 teams (meaning t2 teams that eventually make it into t1 are at an extra disadvantage)
I dont exactly want another situation where, for example, Italy and Portugal have almost 0 representation in their merged league, but its also clearly not working atm, so you gotta pick a poison
