Possible new champ

So I was thinking about different styles of champions and game play as far as team comp goes but theirs not really a champ who gets punished for helping his team, So I thought maybe we need a champ who is a melee/AP based/tank that requires a lot of spell vamp, ill give a brief description of how he will look I am still working on the concept art for him but the basis of him he will be the same character size model as Azir, He will wear a full black cloak that covers his entire body but his eyes, but his eyes one will be lower than the other he wears black shoes but you cant see his legs and his character model floats but he has no hands their gone he wields a staff but he ii not a ranged champ , That is where his abilities come into play, which is another part of the process i am working on so far this is what i have plans for but they might change , His Q will make his staff empowered with a dark aura that gives him an increased ranged auto attack that applies 80 % of his ability power at max level, His W will give him a shield that increases his armor and magic resist by 5% but only lasts for one ability then it disappears, His E which will be quite interesting he will have a skill shot where he throws his staff to a targeted location that causes a short range mini fiddlesticks alt but not as powerful and if the player builds spell vamp his E if it connects to an enemy champ will activate the spell vamp, the E also works like ori's ball or olafs q it only stays at a target location for a short duration but the champ can pick it back up and if they hit a champ directly with the staff it slows the target by 25% for 2 seconds' Now time for his R this is the interesting part his alt will work like a mix of Oriannas ult / fiddlesticks/ galios alt , i know that seems ridiculous but let me explain which will lead into his passive a bit when he throws out his e he can activate the ultimate wherever the e lands if he hits an enemy champ with his e before he casts it it will pull the enemy champ back toward the middle of the alt if he hits a champ with his Q before he ults it adds the Galio taunt effect, time to go into what his passive will be the more allied champs near him the weaker his damage is but it makes him more tanky and gives his team a slight increase in movement when all 5 team members are near each other. When he has no other team mate near him he uses almost 100% of his ability power on all his abilitys with each added team member it drops by 10% making his abilities only hit for 60% instead of 100% But it increases the damage he can take and makes his W last longer. He will be a very strong solo lane champ but also has enough in his kit to make him useful in team fights. i am still trying to decide where he should come from and figure out his lore i have an idea for his name but it can be changed so far i have : Aurotin The Demon Staff, its not great i know i just couldn't think of anything haha but thats what i have so far as soon as i can get the concept art done i will post it immediately.
