Barbecue and Chili isn't OP anymore - we all have to stray away from the attempts at proving otherwise. It's a balanced perk that only works efficiently in the hands of skilled Cannibal players, and while that high skill threshold may also mean that those players who can master its usage have an extreme advantage over other players in trials, we still have to account the sheer number of survivor perk builds which can outplay a well-positioned and well-thought BBQ build.
Rest assured, BBQ is a fun perk and I will definitely continue to use it.
