Transfer BBQ&C's extra bloodpoint gain effect over to Monstrous Shrine
Barbecue & Chili is already plenty powerful and worth running without the BP gain effect; it really doesn't need it. One perk that desperately needs a lift though is Monstrous Shrine, possibly the most useless in the game for killers right now, since Bitter Murmur was buffed. It makes sense that the Entity would give extra rewards for killers bringing survivors to its special underground worship shrine!
Maybe transferring the aura revealing effect over to MS instead could also work; in that case, the aura would have to be visible for much longer than usual, to compensate for the fact that basement hooking is rarer and that the killer takes time to climb the stairs back up.
Disclaimer: I'm a killer main who runs BBQ&C on almost all killers. So yes, I'm technically hurting myself with this suggestion, but it's for the good of balance.
