QoL Change for Gangplank (maybe Sivir)

I know we rarely see our bilgewater pirate in the competitive scene this year, maybe some changes are in the works for him, not sure.

I think one change that would allow for more enjoyable gameplay and remove clunkyness would to make his E, Raise Morale, able to be cast while moving. It doesn't feel right that you use a ability to catch up to the enemy, but have to stop moving momentarily to do so. He's suppose to lead the charge for his comrades.

Also, I'm not sure if Sivir's ultimate behaves the same way as they are both similar, but if it does, it could be a nice change for her too. It's not a big change, just something to help with the pace of the chase.
