he doesn't really need the increase attack speed, what he needs is to make his passive requirement like Siege's so that it doesn't need him to be the one who kills the target, just the target dying in his adjacent spaces. unless they have no plan to completely rework this passive (as this doesn't really go well with his heli-drop operator role) and that they really want him to be a stationary operator, this buff would really counteract the problems he has with his S2 (imo his S1 is already great) since you can just drop him early on and by the time the more dangerous enemies comes, his low def (which, again doesn't really work with his heli-drop role) would be counteracted by the max hp increases he got from all those earlier kills
