Champion Concept - "Awaken Trailer" Clan Ferros Guard (Jungler/Support)

As I was rewatching the League of Legends "Awaken" Trailer again and again I started developing an Idea for a new champion. I wanted to share my thoughts and ask for some constructive criticism and, if desired, changes to the skillset I came up with. Comments that go like "this Idea is stupid" without further explanation or factual reasoning are not welcome (but unfortunately unavoidable).

All the numbers are provisionally and might need balancing.

Lore I'm not big on lore, but the new champion would be a henchman of Camille, an elite guardian of the Clan Ferros, armed with a Shield and a Pistol Crossbow. (For the approximate looks, watch the trailer I linked. At about 0:54 they show up). Add your extra lore here :P

Skills

P - Anticipation (self-targeting smartcast) After being out of fight for 15 seconds you will block the next incoming attack or ability and perform a counterattack for 25 (+x) physical damage.

Q - Breach (direction-targeted) You run in the chosen direction for a given distance. Champions standing directly in your way will be stunned, champions standing in close proximity to your path will be pushed aside.

W - Hextech Flashlight (conic selftargeting) You activate your Hextech Flashlight, lighting a given area in a cone in the direction your champion is facing for 3 seconds. Hidden/invisible Champions in the cone's Radius will be revealed. Activate the skill again, within 1 second after the first activation to blind and disorient champions within the cone of light for 0.5 seconds.

E - Tracer Bolts (passive + skillshot) Passive effect: Your every 3rd autohit will put a mark on a champion for 5 seconds, up to 5 marks in total (you can have marks on multiple champions, yet, only 5 in total). Every newly stacked mark refreshes the already applied mark's duration. Active effect: You shoot out a tracer bolt. The first Champion getting hit, will leave a tracer trail behind him for 10 seconds. While on the trail, allied champions move 15% faster.

R - Most Wanted You open fire on your marked targets, dealing 150 (+x) physical damage per Target. The Damage dealt is increased by 5% per stacked mark on a target, up to 25%

That's pretty much about it. What do you guys think? Reminder: Please only constructive criticism. Save your hate and trashtalk for random 5v5 games, please ;)
