Mmm, I do agree my good sir. I think there are quite a few skills in the game that could use at least a small amount of fiddling with if for nothing else than to make the game more “professional” for lack of a better term. I’ll use League as an example since its another game I play; not every item in league is a super viable meta thing, but at least every item does what it says it will.
Edit~ Also, though I think this has more to do with the maps in WvW rather than the skill itself, scorpion wire ends up being obstructed my nothing more than a pebble on the floor or a slight rise in the ground more often than not when I roam with it.
