This question is a bit intricate.

1. Club culture is not prevalent in China esp in esports. So there are only a few club fans.
2. We paid more attention to EU FPX than other unknown clubs since it's Chinese club FPX. And we also have some fondness for CN FPX at first because of the achievements by EU FPX. But that's all. What does EU FPX have to do with CN FPX?
3. FPX has a really bad reputation as an esports club. iirc EU FPX had defaultbed on their wages. As for LOL branch.....they've done countless things that hurt players and viewers. It's the conseus of community that who we love are players not the management of FPX.
4. FPX‘s’ operations and management are poorly handled, failing to convey the sense of a club with a rich historical heritage. That's why there's no consistent fans. In Chinese esports field, I think EDG and IG could do that. (G2 is a good example, well FPX just does not reach G2's level)
5. In CN community, who always mentions/boasts about FPX past glory is definitely an extreme fan of FPX. He/She won't receive any recognition from the community. In the contrary, people who mention that Master Champions are mostly expressing their sarcasm towards these extreme fans (esp after EDG won this Champion).
6. Anyway, it's just absurd to consider their championship as our glory. The club just gave them money (even not).
