The following Champion-Design is just something I radnomly came up with.
All I want from you is to answer 2 seperate question.
1. Is the Kit well designed?
2. Do you think Riot would implement this Kit if they came up with it?
I will not got into numbers, just outline how the abilities work and scale.
P: For every basic attack, gain a stack (capped) that grants bonus Health until out of combat.
Q: Skillshot that slows the hit Target. If the skillshot kills aUunit it will trigger an explosion that briefely stuns sorrounding Enemies and deals damage.
W: Gain Attackspeed for a few seconds. During that time deal max.Health Magic-Damage (scales on AP).
E: Dash into one direction and gain a shield (scales on max.Health) based on how many large Units, large/epic Monsters & enemy Champions you dashed through.
R: With every basic attack a bonus meelee-attack strikes the closes Enemy in range applying on-hit effects (counts as ranged attack for Runes, Tiamat and Wit's End. Also does not trigger a Runaan's bolt).
