Champion concept - Lithra: Piltover's prototype

I decided to make a champion concept that I have thought about for a while. So sit back and listen -

Lore- Underneath the fame of someone great lies a defeated competitor. One such a person was Lithra of Piltover. Always top in his class throughout most of his life, his goal was to become the greatest architect in technology anyone has ever known. That is, until he met Heimerdinger. Amazed at his creations and intelligence, Lithra was determined to defeat Heimerdinger in the race of technology. But his overconfidence was his downfall... Lithra was defeated horribly and humiliated. But Lithra never gave up. Secretly he continued his research and continued to work on inventions. Once again determined to defeat Heimerdinger, he spent all his time working. That is, until he discovered that Heimerdinger had joined the League of Legends. Such determination was rare in the city of piltover. Lithra was so determined to defeat Heimerdinger, he joined the League himself.

Skills - (Lithra's Damage is increased by AP)

Passive: Determination - Every time Lithra looses 10% of his hp, he gains some Determination.  Gaining Determination will increase the damage of his abilities and gives him 5% movement speed per stack of Determination.  (max 5 stacks).  Determination will dissipate over a small amount of time.

Q - Arrow of Confidence(CD- 10sec/9sec/8sec/7sec/6sec): Fires an arrow that deals damage and pierces enemies. Additional targets hit reduce damage my 10% (max damage reduction up to 70%). If a champion is hit, it will mark them with Line of sight. If two Arrows of Confidence hit the same enemy champion - Lithra will gain a small shield.

W- Turret deploy (CD:30sec/26sec/22sec/18sec: places a turret that can be manipulated by his other spells lasts 180 at rank 1, 150 at rank 2, 120 at rank 3, 100 at rank 4, 80 at rank 5. (max turrets at one time - 3) Does not grant vision. Use by Q - Fires an Arrow of Confidence. Can fire arrow even when Lithra is not near it. Use by E- fires a shot that slows enemies but deals no damage

E- Surveillance Drone(30sec all ranks): Active- places a drone that covers an area along a fixed path. If any enemy champions are spotted, it will fire at the champion dealing damage. Eventually it will explode once time is up or runs out of shots (max 10 shots). If cast on enemy champion, a drone will appear and shoot 5 shots that deal damage and disappears. Passive- Line of Sight: Enemy champions hit with Arrow of confidence or two auto attacks are applied with Line of Sight. Line of Sight will can be triggered with E's active immediate cast on champions that will doubles its damage. [ to make that not confusing - If its hit with Line of Sight, the immediate cast of Surveillance drone on a champion will just double its damage]

R- Super Destructive Laser Cannon (CD - 120sec/100sec/80sec): Player has opportunity to draw a line that deals Damage. For each stack of Determination, the damage is increased by 10%.

Since Lithra is an all-out damage mage, he has some pros and cons

Pros - Can quickly deal out tons of damage.

Cons- no escape maneuver.

Tell me what you think please. :)
