Trapper buff isn't good enough.
First off, I want to say that this is a step in the right direction that they've buffed him... but it's such a minor buff that it won't really change Trapper too much at all.
Okay, so you can reset traps. A nice little feature.
But will this help him in the early game? Not really.
Does this mean he has enough time to set up? Again, not really.
The only thing this buff is good for is like saving a second having to pick it back up. You still have to walk to the traps at the start of the game and spend time setting them up. Also, yes you can reset traps... but at some point you're going to want to move the traps to a different location anyways otherwise everytime you reset them the survivors will remember the location of it and disarm it.
It's almost as though the devs are like "We hear you, you want us to stop nerfing killers and start buffing! Well here's a minor buff that won't change much at all just to make you happy!"
