Not just that but PvE, i feel the difference. With the melee point boost on CoE, throwing knives on a percision kill will count both melee and percision points. Id focus on the smaller mobs (vex goblins and hob goblins, vandals and dregs, hive acolytes and thrall) and get 1hKO kills, and with the percision kill knife refund perk, i was having a blast. I cant quite do that anymore. Yeah ill need to damage mobs to get that single knife percision kill, but the fun is taken out of it.
