Nope you are right f launcher naturally has less post cast delay than him. At lvl 75 both launchers can start lvling passives which decrease their post delay by 35% with tactician's contract. It seems even after 2nd awake f launcher has better post delay :<, but I haven't really noticed it. Plus concentrated fire is fun. Fyi I would bind concentrated fire on to a hotkey, no directional input spacebar if ranger rod or whatever your buff input key is. Attack Speed with subwep crusher will depend on emblems/clones, and the same can be said about movement speed. Most lvl 85 epics have some kind of speed increase option in their set somewhere.
