I don't think it should no. Yes they have more range but the problem with their melee is not that it's overpowered but that the Hunters and Titans melee are underpowered (not counting blink strike). Throwing knife can be deadly but its pretty unreliable, Titan melees are powerful and have great abilities but are incredibly close range. The real answer is to give a slight buff to the other class melees. Hunters don't own blink as Warlocks have it too so the nerf to that is already hitting both classes. What should really be nerfed is the titan shoulder charge. Lower the damage a bit and give it a much longer cooldown timer as its too spammable at this point. I'm glad they are nerfing blink but I honestly don't know how they are going to do it. Considering its a jump and not an ability they can't really change the timer much so all that's left if effectiveness i.e speed/range
