Hunters have an execute ability which is powerful but only really when used as a finisher since it is a finisher ability (quite obviously). Though, this ability being a finisher ability, requires ways of getting a target to a low health since that is when it is most effective. Unfortunately, Hunters have very little to do so apart from the basic attacks since rock throws and the knife throw hardly do anything, let alone hit. So this forces us to kind of have to use execute within PVP (Sometimes in PVE when it comes to giant monsters) just like any other move, but then it falls behind, especially when you compare it to the lunge uppercut from Warriors which does more damage than execute can do, along with a some forward movement and even deal damage if you get close enough to someone even though the initial swing animation misses.
I think execute should be stronger to compete or at least have future ways in which it becomes a key combo piece, but in general, having a finishing move as one of our starter abilities wasn’t the greatest idea.
