I noticed recently that Grappling Hook started having odd behaviors specifically in Warsong Gulch, on the slightly hilly terrain, where it’d simply cast, throw the chain out, and not budge my character an inch, despite going on full cooldown.
Now, it’s happening about 2/3 of the times I use it anywhere in Zereth Mortis. Incredibly frustrating in WPvP when it’s supposed to be an escape option, and I just lose an entire tool in my kit due to essentially a big 50/50 RNG chance with seemingly no rhyme or reason. I’ve seen it work up and down slopes, I’ve seen it cancel on tiny bumps on the ground. It cancels down the straight road around the zone. It’s starting to get incredibly frustrating. Not “no path available,” just dropping the cast entirely and wasting the cooldown.
At the very least, there needs to be some protection in place for if the spell doesn’t move you at all so it doesn’t go on cooldown.
