Junglers and tops.
So far we've got 2 teams and the only champ capable of jungling, 
, is also the only real top of the two teams. If riot wants to add a third team can I suggest champs like: 
be added. Just 1 or 2 of those would be fine.
Sarari1 votesstar guardian evelynn is a cool and unique idea ;ooo
Fairyfleur1 votesAs nice as it would be to make a full functioning team of Star Guardians, it isn't worth butchering the theme and putting it on someone that it doesn't fit.
Linna Excel2 votesI agree with this, so riot would have to be careful with the picks. Of the ones I listed in the OP, Kayle would probably work the best and could function as a top and jungler.
Sukishoo1 votesYeah cause every skinline follows the format for making a skin for each lane.... have you seen Arcade/Boss. Those have come out with 2 adcs back to back, multiple mages, ect. Riot just makes skins for champions that fit the themes, they don't have to be suitable for a lane set up.
Besides, 
is perfectly capable of Jungling. Ever seen Korea? :P
