The Ghoul lacks Deviousness, like a bit. (EDIT: Fixed)
Short Version: The Ghoul's Deviousness score events aren't very impactful and make it difficult to max out the Deviousness category, additional or buffed score events would make the bloodpoint gain feel natural.
Longer Version: I've been playing the ghoul for a bit now and overall, he's super fun. Now, aside from some balance changes which you've probably heard from every corner of the community (cancel cooldown, vault speed, auto-aim, etc…), there is another issue which has been bugging me.
The ghoul has a power which he uses very often be it for chase, map control, or just to try out some tricks. But when you actually use it, you get no deviousness points? From what I've seen, you get points for a perfect hit which gives nothing if you're not actively using the brown add-on, For entering enraged mode, and for vaulting a window or pallet whilst aiming at a survivor. All 3 of these events seem to give no bloodpoints whatsoever. And there are no score events for some additional things such as long-range hits, hitting whilst in motion and precise hits (clicking a survivor without relying on auto aim and actually looking at them). The worst offender is that you get no score event for just using a leap which is something that wouldn't be too broken as blight gets a score event for using a rush (which is used just as often). In the 8.7.0 PTB the Houndmaster is receiving some changes due with her deviousness score events. So is it possible that Kaneki gets the same treatment.
As seen in the DBD Wiki, the score events only apply to hitting survivors and vaulting windows which is only one part of his power.
