Gen speeds are fine, here is why
Generators are completely fine, nobody wants to hold the same button for more than 80 seconds by default, the issue isn’t generator speeds, it’s the size of maps. Maps size or the poor map design is the reason WHY some people ran ruin, so they could cross maps that are larger than the bloody sun and not get up to a generator that is at 80%. Now with ruin not able to do this and forcing you to have to shove people off gens, now survivors will be able to get generators almost completely done before you actually arrive to the generator they were working on. I suggest changing the size of maps so that it is possible for some killers who have no early game power, like trapper and Oni, be able to apply pressure easier without having to use ruin. Good Map design=No need for ruin.
