India doesn't have a T1 region, and it's pretty normal, PC isn't popular in India, PC market isn't that developed, you can't conquer a market that doesn't exist yet.
But Riot doesn't totally abandon India, India is a huge market for mobile game, the mobile game is directly oriented toward them, conquer the mobile market, wait the country end being developed and the PC being something everyone have, and you will already have a big market already conquered in the future. I think in 10 or 20 years India might have their T1 region, 2020-2030 is the decades of the decline of China and the continuing rise of India. Also keep in mind that India is 5 times less GDP than China, and their GDP is BELOW Germany, so India is not ready yet for a T1 region.
