I have never once had a complaint about which Victorious skin was selected.
I have mained Janna for nearly 6 years (I accept the downvotes this entails.), Some of my most played champions are J4, Elise, Morgana and Maokai, and Isometimes bring out the Sivir or ** Graves** botlane when I'm having fun.
Overall, been really lucky with these things. If only I played ranked in Season 2, I wouldn't have to murder someone to get the only Janna skin I didn't buy on launch (Aside from release skins.)
