Cause Riot said they're releasing a support champ, so I'm giving them an idea
Support based from Zaun. Uses nanobots as their weapon.
Passive: If a nearby [single] allied champion receives damage thats more than 10% of their max health, after 3s, the champion will automatically heal a percentage of their health back. (20s cooldown).
Q - Artificial Sense: Nanobot can be planted anywhere (up to 2 charges), used as a ward. Takes 6% of health. Lasts 30/40/50/60/75s. Passive: Pick up nanobot to restore 2% of health.
W - Laser circus: Sweeper-like attack. Base damage + slow. Any stealth-based champs caught by the attack will be exposed.
E - Malware: Point-click based. Plant a nanobot on an enemy - ally champ hits champ with nanobot attached to do additional damage + slow. Debuff lasts for - 2/3/4/5/6s.
R - Infestation: All nanobots will infest every enemy champion. Every champion will lose a percentage armor, magic resist, hp regen, and inflict grievous wounds for a short period of time. (Base damage: 370; Cooldown: 140/130/120/110s).
