I'll speak for myself here, but to me there is a difference between fatalities and fart jokes. Fatalities is a form of over the top violence, so needlessly violent that it becomes absurd. A kind of Grand Guignol, dark humour if you want.
For me the best fatalities are not the bloodiest but the most creative ones. My favorite from MK9 is Cyber Sub Zero's with the shuriken, and it's one of the least violent in the game. I think I can create a poll about the favorite fatality so far in MK11 and I'm pretty sure Johnny's would win in a heartbeat.
But, on the other hand, fart and pukes jokes are, before anything else, a lame attempt for humour in poor quality medias. This doesn't mean you can't have fun jokes with that, but it requires to be creative and bring them in a clever way. Here's some exemples :
In the case of Bo'Rai Cho, the repetitive farts and pukes makes him boring by the end of the first match. Bo'Rai Cho has been in MKX's roster for 3 years now and I've met BRC players like ten times, and more than half of those were just after the release of the KP2. I mean there's probably something wrong with him to be that unpopular. I really wish you added a poll with "Did you like Bo'Rai Cho in MKX ?", so you could have an idea of the popularity of the character.
Again, I'm not against the Drunken Fighter concept, but adding farts and pukes to the character is a deal breaker to me. They had the opportunity to rework him, to make him a more serious yet comical relief character, to show who is the teacher of the legendary warriors Liu Kang and Kung Lao. But no, they wasted the opportunity. Too bad, he probably won't get another chance.
I'm pretty sure you can create a drunken fighter in FG without falling in the pee poo humour, you can make the character a bit silly as long he is not ridiculous. It requires talent, skill and creativity to create such a character, but we all know here that NRS has very good artists and can make a good character out of it. I've always claimed that NRS is the best studio in character design in the whole FG industry, but Bo'Rai Cho made me doubt about this statement when he got released.
I'm sorry if your character will not return in MK11, probably not even in MK12, but for many people, including me, that is not a great loss. Not liking BRC don't make us "edgy weebs that only like color swapped ninjas and slutty female characters".
I know sometimes it sucks to like something unpopular or the opposite, but attacking the people that do not agree with you is never a good idea to make others accept your point of view.
Have a good day, sir.
