New Champion Idea: Haidawshin

A new, dependent marksman that can burst down target champions and get away (hopefully) without getting killed. He is basically an assassin/marksman for hire. Here is the idea. (Note that I don't have visuals, lore, or exact numbers on range or scaling etc.) (Also, all of his kit is level ONE stats in this concept like cooldown etc.) First off, his weapon: A light weight pistol that has a fairly long barrel. Passive: A Steady Pace: Every 5 seconds, Haidawshin's next auto attack will mark w/e he hits with a tick of Focus. Each tick of Focus on a target will give Haidawshin 3% of attack speed towards that target only. Focus ticks max out at 5 ticks. If Haidawshin stops attacking the target, the tick will disappear after 3 seconds. Every auto attack Haidawshin does will eliminate 1 second of his passive's cooldown. Q: A Keen Shot: Haidawshin will fire off a special dart/bullet that will mark w/e target he hits with true sight for 7 seconds. Cooldown is 6 seconds. Deals physical damage. W: A Marksman's Bidding's: Passive: Upon slaying a minion/monster, Haidawshin will collect an additional 3 gold. Active: Can mark a champion that will last for 20 seconds. If you are successful at slaying the target you shall receive an additional amount of gold based on level of the marked target. Cooldown is 15 seconds. E: (No name A.T.M.): Haidawshin will leap to an area. Its just a leap. But, when Haidawshin kills a champion it will reset his cooldown on the leap. Cooldown is 15 seconds. R: Time To Strike: When an enemy champion is near that is marked with true sight, Haidawshin's ult will ready to use. When he ults he gets additional armor penetration, movement speed, critical strike, and attack range. The amount of stats from those categories, vary on the amount of true sighted enemies near. Remember, not all of this information of stats and stuff aren't finished. If my idea does get some views and suggestions I may make a lore or go deeper into stats. Thank you for reading this suggestion.
