Grapple shouldnt have a 1+ minute cooldown. Hell I dont even think the cooldown should exceed 20 seconds. The grapple is the entire point of strand. Specifically the mobility it adds. This goes for PvP and PvE. I lose a grenade ability so that I can grapple, at least let me grapple frequently. And if theres a concern about it changing the meta too heavily in PvP (which is fair considering woven mail) then add an armor mod that allows user to do increased damage against guardians that are in the process of grappling so that there's more of a risk/reward mechanic to it and woven mail isn't an easy cheese and can be countered.
