I think what makes the diverticulitis worse was that he had to come back from it to fight a steroid abusing freak soon after, and obviously lost. Diverticulitis can be life threatening on its own, even without having to return to fight Alistair Roidreem. I'd quit UFC too if I had a severe condition and then returned to lose to somebody on roids. He already had proven that a "wrestling actor" can come into the UFC and defeat legitimate fighters, so I think it made sense for him to exit that scene when he did.

I've seen what diverticulitis can do up close and personal because a few years back a family member of mine had to have a large section of their intestinal track removed and it changed that person's life forever, unfortunately. I could be wrong but I think when Brock was going through it, it was considered a very bad case. I believe the pockets that form in the intestines had busted open and he had shit leaking into his insides for a while before it was caught, if the reports I remember reading were accurate. It's also possible the reports were exaggerated, so who knows in Brock's case, but I do know my own family member almost died from the same thing.

Also as for UFC itself, I don't find very many fights entertaining. If you're used to being "wowed" during a match and you're even slightly familiar with how wrestling matches usually go, then the UFC is going to seem awkward and boring as hell when they keep hugging each other and spend half the round wrapped up together on the floor. lol They'd need to overhaul the rules of a UFC fight big time if they wanted it to be constant entertainment. The best UFC fight I ever saw was one that ended in about 3 seconds and I already forget who the fighters were. Some guy rushes in for a double leg takedown at the same time the other guy threw a high knee and the knee knocked out the guy instantly. There was no time to get bored during that one. lol
