New mechanic idea for assassin

The mechanic would include the w which would have a max of a certain amount of charges. It would be a point and click mark or a skillshot on any target, friend, foe, or neutral. E would then be able to dash or blink to marked target with a short cooldown on just that target (like talon and his walls) and the champ could infinitely (well not infinitely because of cooldowns and math but there would be no set about) to that target until the mark expires. Or, you know what? The target gets marked and the champ could jump on them a set amount of time but with a very long timer on the mark.

If someone at the champion creation group of Riot sees this let me know what you think. I think it would be a fun, high skill cap ability with counterplay. I'm not going to suggest what you do with it. You guys know what you're doing. Just thought you might appreciate the idea.
