Got an idea for GP and Sion.
GP: He has(IS) been a number one power source for most teams. But the nerf to his E is a little too much. How about, instead of GP getting barrels when he levels up Cannon Barage, which was removed, how about every time he upgrades Cannon Barrage, he gets a barrel? They already nerfed the Silver Surpent income, so this might be a decent buff.
Sion: He is incredibly weak, and part of that comes from his Passive. How about when sion dies, he becomes immune to CC, this would fix a lot because one leona Q or Gold Card would be the end for Sion's passive. Let me know what you think!
