How Goh Jin Wei can improve her world ranking if she did not even participate in her own home ground 2-tier tournament? For other countries 2-tier tournaments, usually the lower rank local players can participate in the qualification matches even if they are junior players.
There is a practical reason why Indonesia Master fails to attract higher-ranked players. Remember when it was held. Just after Hong Kong Open, the last Superseries of the year. While Malaysia Masters will be held in January, more than one month before the first Superseries of 2016, All England.
For Goh Jin Wei, to improve her World Ranking, she needs to win International Challenge event first, presumably two or three. When her world ranking was in top 100, she can play in the qualifying rounds of Grand Prix Gold. There are also some Grand Prix Gold events that do not attract higher-ranked players; mainly because it was held too near another Superseries events.
Another shortcut would be to play in team competition. When she beat higher-ranked players in team competition, such as Uber Cup or Sudirman Cup. She would gain a whole lot of ranking points. In fact, Lee Chong Wei first played in Sudirman Cup when he was back on court after serving 8-month suspension.
LCW should not participate in this tournament. Instead, he should rest more to ensure he is fully fit in major events like Olympic Games in Rio.
As for Goh Jin Wei, it is good that if she is able to participate. At least, she can gain experience.
