The grapple gun having such short range and limited ammo kills it as a mobility tool. And since its only good for mobility, that makes it almost completely pointless.
I think the grapple gun range should be DOUBLED at least, and it should have INFINITE ammo. So that way it can actually be good for mobility. The tool itself is already completely unusable in a pvp setting.
I came to this conclusion because: sword lunge is better for mobility, and its good for pvp as well as pve. Its easy to do, you can do it unlimited times, and you don't have to sacrifice a weapon slot to being solely a tool. Grapple gun DOES offer verticality, but the range is so ungodly short that the verticality it gives is practically worthless. There's next to 0 verticality in pvp and in pve only some islands would even need it. And the ammo being limited means that useless mobility now gets turned into LIMITED useless mobility.
Overall i'm very disappointed with this, i wasn't expecting it to be this godly boarding tool. But i was expecting to actually do its job well, but it gets 99% outclassed by the cutlass
