Exactly, how they can go to Tier 1 if they are a big skill gap on their server ? Never, the gap will continue to increase, if we dont put mid Indian player in T1.
The best way is to increase India's level, is to pick 5 Indian player, put them in tier 1 team, so they can play on Korean server, improve, have experience of T1, they will be bad in the first year, (maybe a little bit less if they arrive really early to grind soloQ) but in the long term they will surely progress, and when they are dropped out of the team, their experience will help to grow Indian scene.
If we don't do this ? What is gonna happen ? Indian player will continue to play against Indian player, never improve, while Korean player will continue progressing and the gap will continue to be bigger and biggers.
Thats exactly because Inidian player doesnt have the level in tier 1 that WE HAVE TO put the best 5 of them in Tier 1 other way, the scene will never improve. Think long term, stop thinking short term
