Do you find this design interesting? maybe a bit Broken? just read.
Imagine a new ADC with a Giant Bazooka.
But not just a regular ADC, his Auto attacks themselves are slow moving AoE skillshots with 700 range.
However, they deal 300% Total AD and have 40% Total Armor Penetration by default BUT they cannot Crit nor do they Apply on hit effects.
"He could become really problematic with some atk speed"
His Atk Speed Growth stops at level 6. He has 0.5 base Atk speed and this value will go up by 0,1 each level until 6.
However, his Atk speed is LOCKED.
Items, Masteries, Runes, cannot bring his Atk speed up or down.
Only his Ultimate is able to do so.
"But what is his Ultimate?"
His atk speed values are increased by 1.5 / 2.0 / 2.5 for 6 + (0.5 per Auto attack Champion hit).
"But, then Atk speed Items are useless on him right?"
Not at all. Bonus Atk speed will speed up the Animation of the Auto Attack itself (remember they are skillshots after all).
Giving it an interesting mechanic in which his Auto attacks can either become too easy to dodge (when you find yourself with too little bonus atk speed) or too hard to hit, unless the target is right in your face (when you get too much bonus atk speed)
"What about Crit?"
Crit Chance would increase his Auto attack Radius, remember they are AoE
Think of it a combination of both Ryze's new E with Graves Ult.
There is a portion of the missle that will deal Major damage to a target, then deal a bunch of AoE to targets nearby.
The AoE growth is capped at 100% of its normal size. So, twice as big.
Infinity Edge passive, increases the Damage of the AoE itself.
So, what do you think?
Maybe its too broken, but I think its a cool idea.
He has Major Potential but also Major Trade offs.
