I found a bug
So I have an almost maxed epic mech cooldown implant, but it just isn't active. I use my ability and the cooldown isn't changed. For example, redeemers ability cooldown is 11 seconds, but with my implant, it should be 5 seconds. And, with killshot, it's cooldown is 5 seconds, but it should be 2 seconds with my implant. And yes, I do have it equipped. I made sure.
