Champion idea - Razorwire

Champion idea (AD jungler) I came up with. Let me know how you think it could be improved :)

Passive- Damaging a champion gives Razorwire bonus AD for 5 seconds

Q- Backslash Razorwire slashes in a cone infront of him. If the ability hits multiple opponents, he slashes back the other way and is healed for a % of the damage done.

MODIFIED Q Backslash is put on a lower cooldown and also applies on-hit effects to all the enemies hit.

W- It's a trap! Razorwire stings a wire trap between two pieces of terrain. Deals a % of max health in true damage, and the length of the wire increases with each point put into the ability. Enemies do receive a warning however when they get within a certain range (pretty close) of the trap with a warning indicator above their head.

MODIFIED W The wire slows opponents movement speed by a large amount and reveals them if in FOW.

E- Tied up Razorwire lashes out with a length of wire (skillshot). If the wire hits an enemy, it does initial impact damage and winds around them for a maximum of 3 seconds. Staying within the radius (shown to both Razorwire and the enemy that is caught) deals damage over time (per 1/4 second) whilst leaving the area deals higher instant damage (calculated by the time left that could have been spent within the range multiplied by the % damage increase of they leave). Both Razorwire and the enemy have their movement speed reduced during this time, but can use other abilities.

MODIFIED E Razorwire can use the ability up to 3 times within the duration of the ultimate (but not on the same enemy), allowing him to catch multiple enemies at the same time with the ability.

R- Highly Strung Razorwire goes into a frenzy, modifying each of his abilities for a certain period of time and also gives him a small movement speed buff for the duration.

TL;DR Champion idea based around the name, Razorwire.

Q- Cone slash that can heal

W- Trap placed between terrain

E- Skillshot tether

R- Empowered other abilities for a period of time
