The next Ultimate Skin...
We have three ultimate skins, an ADC, a jungler, and a support. That means the next ultimate skin will most definitely be a top laner/mid laner.
Now that we know this, Riot has to make up for last year's ultimate skin. That probably means another is coming this year, hopefully.
Now possibilities of the champions.
Riot has to pick a champion with no legendary skin.
So that means Nasus for example is shut off.
Personally, I believe Riven can be a good contestant for a ultimate skin. Has several skills, and probably can be activated to a great amount, making the sword crazy. So she can be a choice.
A mid laner, possibly Ahri? Ahri is a really good idea for Riot to do.
Let's see what they can do with these two champions.
Darkness Riven for example.
Grows darker and darker as the game goes on, sword becomes much more "powerful". All Q abilities will have a different kind of light, and when she uses her ultimate she gets a whole new kind set of particle effects on her moves. If she does something like ctrl 5 she will go into another mode, Light mode. Will have light particles and such.
So, out of all of this data. We can safely say, it will be a top laner/mid laner. It will be released this year hopefully. Any champion that has several moves to it like Riven or Sona or Udyr are a good contestant for an Ultimate Skin. Tell me what you think. (Udyr and Sona have Ultimate Skins now I am aware)
She starts off almost like a student, she doesn't hover and spell animations look sloppy like she is still learning. Wears a white/brown dress and her hair is tied up behind her. (would occasionally trip or stumble, maybe when casting a spell or somethin)
