Go SEA keep the current roster. Let another org be the Indian rep.
With this roster they will prob continue to be top 3-4 team in SEA and make it to cups.
The risk is that they don't get that slot from SEA because they don't have any base of operations or fanbase there. In that case, they could also try to go from korea (they have history of operating korean teams in other eSports too) they'll just have to get 2 koreans for xavi and kristal. But the issue will be korea will be a very competitive region so it's possible they don't make it to cups.
Overall I think SEA is the most balanced option (given they have a decent shot at getting the slot).
