I've given a bit of feedback on this before, but I'll just say this to you @chris-houlden and anyone that feels similarly:
I understand feeling negative about the possibilities of in-game content creator rewards. It can easily fan a have and have-not issue that nobody likes to deal with - never mind the things already stated (that creating content already comes with its own rewards and benefits [when the content hits well with the community, at least!]).
My advice, however, is to not let it bother you that much. I mean, I get it - our feelings are our feelings when we initially experience them. When I get those sorts of negative feelings over what a game I love will be doing, I just step back, and take into consideration 1) it's not that big of a deal 2) it probably won't be anywhere near as bad as I can imagine (and even if it were, it's not even that bad anyway), 3) they have their reasons for doing what they're doing and maybe it will be good for them. I take some breaths, smile, and carry on doing what pleases me and not dwelling on the things that bug me so much.
That being said - when more information becomes available and if anyone disagrees with what they're doing - by all means, share your feedback and offer your criticisms (always best if combined with alternative suggestions). The community is much more than streamers and Rare will never fully lose sight of that. Part of this is and will always be business. And we all have to accept that. Plus, I think there are legitimately good reasons to continue to engage and foster the content-creating community beyond business/money.
I believe that the people at Rare truly love the content, are somewhat humbled by the people behind that stuff, and feel a desire to pay it forward by giving more to content creators and such. It's not all about the money (even if it is ALSO about the potential money).
So, it's not all bad - and might not even be bad at all. At the end of the day, if there are some cosmetics earned through this stuff - and more focus is continued to be given to those who choose to prop themselves into the spotlight by streaming and making videos and such - eh, big deal. That's today's society, right? Maybe there'll be a reality show spin-off of this - SoT Streamers on an island... :D :D
Me? Even as someone that streams (and long planned to make some edited videos and tutorials - but STILL HASN'T LOL) - I would rather avoid stoking the flames of the streamer vs non-streamer animosity that sadly exists in today's community. However, they obviously are very excited about it and - who knows, perhaps it will be fantastic. At the end of the day - it's not like they'll be spawning Shrouded Ghosts based on your viewership numbers! :D (Umm, yeah, that would be horrible, haha!)
