The killer that i really want
We've had Bear Traps
We've had Chainsaws, twice
We've had turning invisible
We've had teleporting, 3 times at this point (2 of those are a technicality but you know what I mean)
We've had stealth and stalking, twice, 3 times if you count Pig
We've had Electrokinesis
We've had dream manipulation
We've had biological warfare, twice
We've had run fast and stab
We've had the personification of the term "Blood Rage"
We've had guns
We've had literally sending people to the depths of hell
We've had Pinball
We've had Divide and Conquer
and we've had knife tricks that make DIO blush
and now we're getting Biological-Warfare number 3
You know what i really want?
A killer based on fire
Genuinely surprised we haven't had a killer based on one of the most common elements used in fiction, Fire has so many possibilities for use in DBD
It could be used as a projectile for instance (mage character maybe?)
OR it could be used for map manipulation (temporarily destroying windows and creating fire walls to block off doorways for example)
There are a lot of ways you could about designing a killer around this too
For some examples, you could have
Arsonist
Firefighter
Street Performer (Yes fire-swallowing was a real thing)
or, and my personal favourite, Dragon
Seriously BHVR, when you guys get done with RE consider listening to Through The Fire and Flames for a bit and making something based on this, i REALLY want to be able to burn my mortal enemies to ash

Freddy is already sort of based on fire (I am pretty sure). It is kinda weird how he doesn't have any flame or fire associated with how he looks at least aesthetically which is kind of a bummer.
