More Trapper-Treatment please!
Trapper getting 2 traps by default was an amazing change!
Personally I would love to see all killers getting some minor adjustment.
My suggestion would be to look what add-ons are predominantly used on each killer and implement the raw number changing ones into base kit, while simultaneously removing and/or reworking the now obsolete add-ons.
When a majority of the playerbase already are using these add-on and even already considering them base and without them the killer is less fun or even unplayable in some rare chases, we might as well make a healthy version of them base kit and allow the killers for more innovative and creative builds to see play instead of always the same add-ons.
I really love how some killers have cool add-ons that change up their playstyles and as a player you can switch em up and adjust to your own preferred way of enjoying the game and not everyone playing them so samey.
