Post here what bad effects some skins may have so that ggftw-ers know what they're getting when they buy something.
Sewn Chaos Orianna - she throws the same clockwork items her classic skin throws though this skin has no such items on her and would look so much better if she'd just throw those pins she has on her instead.
Arctic Ops Kennen - he uses kunais instead of shurikens but his auto attacks and his Q involve him throwing spinning kunais.
Lion Dance Kog'maw - his E skill is a regular slime roll despite it being a legendary skin.
Nunu Bot - nothing new other than phrases and general appearance. No new particles, animations.
