Yeah, I'm just thinking making the b.3 a bit faster on the pick-up would allow for more combo potential for the character himself, and would probably help with some of the drops that may occur within the tight links Flash combos are infamous for. Its more a quality of life for people not as savvy with the quick inputs (like myself) while not breaking the bank since, generally, its the same move that simply puts more control into the hands of people using it while not making it something that can be thrown out mid-combo by itself.
Trait, although I agree it ~can~ be used for footsie tools its cooldown is incredibly long and is better spent doing the damage as it is now. Increasing the duration and scaling means it can still be used for combos, but its not necessarily the end-all optimal choice that you have to neglect the neutral state for. Meanwhile, decreasing the cooldown helps offset the damage scaling by ensuring you can go into trait more often (not significantly so). But as I said, its just my opinion.
