To add a bit more context to this clip, my concerns are about 50% BFA and 50% stream-specific.
What I mean by that is while BFA is still something that I play off-stream and even accidentally enjoy on occasion, it's not something that my audience seems to enjoy watching. This creates a pretty big disconnect between what content my audience likes and what I feel is creatively fulfilling.
While I love to do transmog contests, mount-offs, and other events, you can only do them so many times until you get bored. In Legion this was of course a problem but the difference was that many more people seemed to be intrinsically interested in content outside of contests because they were engaging in that same content themselves. In BFA I feel that a lot of my audience has lost interest with the game and conversely lost interest in consuming content that's centered around BFA.
This is compounded with the recent jump in popularity that I've had that literally more than doubled my metrics (viewers, followers, subscribers, etc). It put my stream in front of a lot of new faces, many of which don't even play WoW. In fact, according to my Twitch analytics, only 17% of my viewers have actively consumed WoW content on Twitch in the last 7 days. Because of that growth, it's caused me to make my content more accessible which leaves out a large swath of activities that novice and non-WoW players don't understand or appreciate (mythic raiding, high M+, high end arena, etc). It's easy for someone who doesn't play WoW to understand and follow along with a transmog contest but it's a lot harder for that same person to follow along with a M+15 Freehold.
I would also be lying if I didn't acknowledge that BFA itself is partly responsible for my disillusionment of the current game. It's shallow, dull, meaningless, and not fun. On a personal level, I do not enjoy playing my character. I don't find M+ fun at all, it's boring, repetitive, and mostly trash. I could go on and on but I'm sure anyone who's familiar with my content knows what I'm going to say.
It would take realistically 3 or 4 expansions for Blizzard to undo all of the mistakes and missteps they've made with the current game at this point and I fear that in the expansion after this, that number will go to 4 or 5 rather than 2 or 3. The developers are fundamentally disconnected with the playerbase on an emotional and psychological level which is what leads to the many instances of Ion explaining to us that we're having fun in the wrong way.
I don't think I'm ever going to stop streaming WoW, but I do think that I'll start streaming other games too. BFA has made that a clear necessity and also my own creative expression isn't fulfilled by just WoW streams anymore.
