GP Buffs Ideas??

Not saying needs to be focused rn with buffs atm but I do feel very sad stormrazor got reworked. Gp was top stuff when he could still go full lethality into SR and now he feels 'so-so' again and this feels bad man as a gp main. I feel if he was to get a buff it should either be

A.) Getting mana regain back off from last hitting with his Q. ( Think Annie q mana regain. I think that would make him good in the mid lane again like he use to be back in season 7. At least sustain better in lane with mana. )

B.) His barrels gives grievous wounds. ( Now i know this probably sounds like a super op idea and would probably causing top gp to run amok against tanks but i'd love that idea.)

Other GP mains or anybody else whats your thoughts about this or GP's position rn?
