honestly, with the frag and maxed discipline it barely moves the cooldown (at least on warlock) it's still a pretty shitty cooldown. i'm pretty sure the strong limit has consecutive grapples without touching the ground in mind, i dont think it's a lot asking to be able to use the grapples more often since i seriously doubt anyone's used it for anything terribly crazy during the campaign trials. i honestly think the long glides you can do with a built dawnblade class is way crazier than the 5 second strand grapples were. there's little use for a movement ability like that when it blocks a grenade slot like it does.
