New Void Champion Concept

So this is being going through my head for a while that their has not been a new void champ in over three years and so i came up with a AP support that only has to stay in one lane all game probably but not really came up with a good name for it though and i'm still working on the design but with out further a do i'll introduce to you Xel'Kar the seeing. passive: The eyes of Xel'kar allowing him to have increased sight and auto attack range with each level and cannot buy wards but is replaced with The Void's Gaze Q: Pillar of Hope, Xel'Kar places a small pillar of the void on the ground for 20/25/30/35 seconds which will act like a heimerdinger turret(attacking minions but will switch to the nearest enemy champ hit with Xel'kar's most recent AA) and scaling with 60% of his AP W: Void Safeguard, Xel'kar upgrades his E for 20/22/24/26/28 seconds as well as refreshing its life span and allowing it to both shield the chosen ally for 2% of his maximum health and have ranged attacks scaling of 20% of his AP, if his E sees an invisible or camouflaged enemy champion whilst W is up it will not attack the enemy champion E: The Void's Gaze, Xel'kar channels for 2.5 seconds to the chosen ally champion to place on of his on the chosen for 10/15/20/25 seconds and acts like a sweeping lens and can see both camouflaged and invisible champions but only Xel'kar and the chosen ally can see them R: Sight of the Unknown, Xel'kar uses all his mana to see all the enemy champions for 5/7.5/10 seconds as well as putting his E on all allies well that's my idea and i hope you like it and if you think i need to improve or change a few things just write a comment and i'll respond as fast a possible.
