As a Killer, the game feels bad if you don't 4K.
IMHO: This is the biggest problem with playing Killer at most levels of DBD - if you don't 3 or 4K, the game feels like you lost.
Take Survivor, you can still objectively have a fun, rewarding experience even if the killer 3Ks. Hell, sometimes even dying to insure the killer only 3Ks is still a fun, rewarding experience.
Imagine how bad this game would feel like as a Survivor, if even if you escaped, you felt like it was a loss unless everyone also escaped?
Yet, playing killer, failing to kill 2... and watching the survivors teabag you in the gate until you eventually escort them on their way feels like a loss.
Whether this is a community created perception image or something the game somehow cultivates, I think everything would get better if they found a way to fix this... because right now the Devs balance the game around 2 kills, 2 escape. Because of that, they're always going to seem to be against killers... because the very nature of their game design is to balance the killer around having a game that's perceived (by the community) to be a loss.
The game needs to feel better for a killer who only gets 2 kills... if this is how the Devs want to balance it.
