But that is what i mean, it requires personal investment and muscle memory, that's it.
Being good in reactive, competitive gameplay requires you also to invest time - into your life. E-Sports is the word, like any other "Sports" it requires a healthy lifestyle to have your body and mind in good shape and outperform others. Also it requires the same or even a higher level of communication skills with your team.

Let them get viewers, that's just a part of community building, it doesn't seem wrong to me. FFXIV has a lot potential, also for pvp content, you are blind if you can't see that. But the community needs to show interest in it, so the producer will find it worthwhile to invest into that.

I'd only stream for the mere reason of others asking me to watch to maybe improve or tell me what I could do better.
