I finally finished mastering the pulse grenade commo. Now all 3 grenade commos are finished. Certainly different grenades work better in differing games and environments. Those that do think grenades are useless may be using them in the wrong map or game. It would be nice to be able to switch grenade type in-game without going to the loadout, but I don’t think that’s on the menu.
As with anything else grenade chucking takes practice. Which I need because I still can’t kill 2 people with 1 pulse grenade in a Majestic DLC match.
