Champion Concept: Kill Joy, the Hextech Healer (An ADC Healer)
As League of Legends gets more and more champions I start to think, what mechanic or playstyle isnt in the game yet but would be pretty cool. Here's once. An ADC that can choose to auto attack minions to deal damage or allies to heal them. (All names are up for change lol, just made up names decent enough to fit the abilities)
Attack Range: 425
Passive: War Medic - Every X amount of auto attacks, Kill Joy releases a small AoE pulse from his body healing all allies in range for a flat amount of health.
Q - Death Ray / Healing Pulse: After autoing an enemy champion 5 times, this ability can be activated. Your next auto can be targeted at an enemy dealing bonus percent health damage based on your total AD or you can target an ally and heal them based on their missing health.
W - Boost: Killjoy 400 range to target location, every 3 autos on an enemy champion lowers the cooldown
E- Scan: Killjoy scans an area on the map, if an enemy is there. They are revealed for the next 15 seconds. (Long Cooldown)
R- Self Destruct: Killjoy explodes after a 2 second channel, dealing AoE damage based on his missing health, the more health Killjoy has the more damage. After another 2 seconds, Killjoy rebuilds in the same spot but is heavily slowed for 1.5 seconds.
As you can see Kill Joy wouldnt be the best scaling ADC or the best laning ADC but where he shines is objective control and team fighting. With his passive he can keep his support or anyone near him alive for long enough to turn the tides, or with his Q he can deal a chunk of damage to an enemy or a chunk of healing to an ally, thriving best in chaotic 5 vs 5 where he isnt focused down. This would allow for him to sustain his allies enough to change the out come of fights if played and positioned correctly.
