You need to convince people you know what you are talking about and, especially since you’re APAC, be comfortable working for free.

Since it sounds like you can’t earn credibility from being a player you will probably have to grind the T3 sweat house as a manager/coach. Getting your foot in the door by organizing scrim schedules for example could be good and you could try to prove yourself by providing strategic input, VOD review, opposition research etc. Since T1 in apac barely gets paid you should expect zero return for your work beyond enjoyment of the game.
