Custom Gamemodes

Hello all,

I am really bad, not at english but, in general talking so this will sound complicated.
I was playing KYF the other day and we had a couple of awesome gamemodes such as kill people with hatchets while they run in the field of corn, or hide from myers before he mori-s you and get the trap off your head before it explodes.

But all these had a problem.
Huntress ran out of hatchets and had to go and get them.
Myers had to hook every1 in case he found some1 in a locker.
Piggy didnt have a terror radius big enough to affect skillchecks with unnerving presence and survivors would sometimes get the trap off the head on the first (wouldve been nice if they all needed to do all 4 jigsaw boxes to get it off).
Of course none of these are actually problems in game cause it would be too powerful but in custom gamemodes it is.

SO my question is: Could we get custom gamemodes in the game? Or give us what dota, warcraft 3 and starcraft 2 have: the ability to create these modes (would surely be easier for you) and i believe people would be at least happier! These ARE gamemodes which you get tired from pretty soon so it shouldn't affect the original game.
Think of it as a "stress dealer" where people go to deal with stress.

Sincerely,
HalflingHR
