Last gp nerf was abit rough...
What the title says, now it may just be me having wrong masteries or runes, but Mana returned for killing a minion is very low now, and his barrels seem to do alot less damage for being a Prepared skillshot that can be easily canceled. Why not take the nerfs you did to him.... Revert them... and add half of the Nerfing that you did. I played GP rework at its prime, and now i can see why not that many people play him.
(i do know that i still suck with him but these are things i noticed.)
