Jarvan IV 2020
With all the change in Demacia recently I think this is the right year FOR THE KING 
I. Lore update
With the death of king Jarvan III, it is time for a new king to rise. And there can only be one true king . From there his story can goes in both ways. Either he has a change of heart and reconcile all mages or he continues his dark path and becomes a tyrant. Only time can tell how his story goes.
II. Champion update
 is an old champion, but most of his kit stood the test of time. So what he needs is a treatment like , a VGU with his W replaced. I have already create a discussion about this issue so any suggestions are welcomed.
III. Ultimate skin concept
Since 2020 we will have an ultimate skin, I would like to contribute my ultimate skin concept called : Ruler of Runeterra.
-
Concept idea The skin theme is about 13 regions of Runeterra. The way this skin work is kind of similar to how Elementalist Lux does. When the game start
will represent the region of Demacia, as the game progresses he will choose which region to "rule" just like how 
choose her element. Since there are 12 regions left, we should split those regions into 4 groups, each group with 3 tiers. So whenever upgrade his ultimate he will be able to choose one region from each group. Currently I don't know how to split this so any suggestions are welcomed. -
Visual Idea
armor and weapon should represent the region he chose. Here are some of my suggestions for the visual of this skin :
Q : Depends on that region favorite weapon.
W : Animation have the icon of that region in the center.
E : Replace the flag with a banner of that region and have an aura around its area of effect (Example : Demacia - Light, Freljord - Ice, Shurima - Sand)
R : Represent the architecture of that region

IV. TFT set 4
Since set 3 is already under development, I would like to contribute my idea for TFT set 4 : Rise of Runeterra. This set will be like a combination of both set 1 and set 2. With about 4 favorite champions represent their region and of course  : Ruler of Runeterra as the ultimate tier champion.  will perform his role just like  did in set 2.
