How bout changing shen's scalings?
I'm just wondering about what could make Shen more impactful and I gotta say, changing his Q to AD scaling would benefit him more than AP since he barely builds any, his W shield should be based off his Health or Armor stat (because it makes more sense), his E could use a lower energy cost or scale off his Armor/Magic Resist instead(so he can actually still benefit from his tankiness in other ways) and, I also think his ult shield should be based off Armor/Magic Resist or his health. I don't know if these are the best fixes for him but maybe it will make him better in some ways?
