The ones who kick me out right before the mission or survival ends.
We were on the last wave of the survival i went into every round with the most kills and we get to wave 9 i'm the only one really shooting i already had a majority of the kills under my belt and we were almost done all we needed to do was shoot down the helos then i get a text msg "Okay kick him out now" he sent it to me on accident so i got on my mic and said "I'm not going to kick him out he's helped this whole time then the host gets on his mic with a squeaky voice i might add and said "naah cuz he be sending that to me cuz we be kicking you out" and i was kicked out a second later.
I sent him a msg asking him why i was booted from the survival he sent me a msg back saying "Caah ahh feltt like it" and yes that's how he wrote it
So you do the mission like everybody else but don't get any of the rewards because they kick you out after you've helped them complete 95% of the mission.
I'd understand kicking me out if i wasn't doing anything to help but i did just as much if not more then what they did.
I know i'm not the first person this happened too and won't be the last R* needs to fix this so even if a person is kicked out they should be rewarded for what they did in the mission.
(i.e the RP for any kills you got and objective you've completed such as picing up the briefcase)
Or make it so you can't be kicked out at the last moment i don't know how they'd figure it out to see if you actually helped in the mission or if you were one of those people who just stand around and make everybody else do all the work but they need to figure something out.
