How about, we base gen speeds on killers?
Had this thought early while posting about genrushing. Some killers are far more vulnerable to getting genrushed than others. One of the reasons I almost never play twins is that it takes too long to get anything done. If you down survs with victor it often takes ages to find and hook them. Trapper is a slow killer and makes for a more tactical game. Whilst killers like nurse can end chases super quick, wesker has traversal, blight has both.
Ive suggested before a rolling handicap based on which team is winning, based on gen progress, hook states and how many survs are alive. But since a killer is a static factor in a game, i.e. they are there for the whole match and will not change, perhaps devs vould look at killrates, match times and gen progress times to identify which killers are suffering, and tweak to slow gen speeds in games involving those killers, or vice versa for killers that are dominating and perhaps buff gen repair speeds in their games.
