Jayce and ARAM?

So I have been snooping around for info on the new upcoming stuff for LoL in the new patch and stumbled on the abilities for the 100th champion for LoL and the new All Random All Middle map, a custom game like dominion were there is just one lane and when you die you swap to a new hero but keep the items bought and the level you reached.

Passive: Jayce gains 40 bonus Movespeed and ignores unit collision for 1.25 seconds after each shift.

     Hammer Form:

Q – Thunderstrike: Deals magic damage based on % of target’s max HP and knocks target away.
W – Thunderleap: Jayce jumps to target location, dealing physical damage and applying a slow to all enemies hit.
E –  Shift Cannon: Shifts into cannon form, gaining increased range and new abilities.

     Cannon Form:

Q – Gate of Speed: Jayce summons an electrical gate boosting the Movespeed of teammates passing through. If Jayce’s ranged attacks pass through this gate, the projectiles gain damage/range/speed.
W- Energy Charge: Jayce charges himself with electricity, gaining attack speed for a few attacks.
E- Shift Hammer: Shifts into hammer form, gaining passive armor and magic resist and new abilities.

R- Lighting Field (Both forms): Passive: Jayce gains Mana on Auto attack.   Active: Create a Lighting field dealing AoE damage over time.

I have only found his voice but he reminds me of Zeus in Dota. This guy seems like Kennen's big brother he has a strong nuke and movement speed buff with his Q. A gap closer and adrenaline skill with his W. A rang increase and defense buff with E. Finally a AoE spell for team-fights with his R. Any hero that games two abilites from a single spell is strong in my opinion for the amount of utility they bring to a team. The obvious example is Lee Sin and it would be nice to have another hero like him in the League :D
