The ninjas are easily butt hurt, anything even a bit offensive is bound to be taken down and given a warning for. Even if many worse non-joking versions of it exist. In fact just leave this place. You'll be banned for a bs reason before you get reacquainted with this new waste land.

Be prepared for 1. Destiny shit 2. Destiny shit 3. Destiny shit 4. BLM shit 5. Political shit 6. Brag posts about guns and knives 7. Weeb shit 8. Destiny shit 9. Political shit 10. Selfie threads where everyone is now a woman

Well I think aside from the UI and aesthetic changes which I'm sure you've already taken note of, and the obvious shifting of user population, one of the biggest changes is that they've effectively stripped away any and all of the attraction that bnet groups once had. Which is terrible, that was probably my favorite part of this website during the halo 3 days. Also, by excluding any users who haven't played Destiny, they pretty much casted away any of the older lingerers. Besides that, everything else has been meaningless interface changes here and there, stupid drama, and different sects making their own offsites. I can't think of anything super important happening since Reach tbh.
