Champion Idea, Voodoo (placeholder)

i had an idea for an interesting ult, my friend and i rolled with it and this is what we came up with, a new support, all numbers are kinda arbitrary and there just to give a general idea of the champ.

Innate Passive:

VOODOO gains a buff that is not copy-able by VOODOO's ult every time he returns to shop, next allied champion VOODOO right clicks he Links to target allied champion. VOODOO can only be linked to one Champion at a time. While linked champion is within a 750-unit radius of VOODOO, all movement related buffs/debuffs applied to VOODOO also apply to the linked champion. (VOODOO flashes in a direction, the linked champion also flashes that direction, but only uses VOODOO's flash) The linked champion is slowed for 50% of what VOODOO is slowed for (80% slow on VOODOO is a 40% slow on linked Champion (same duration)). Any stun/knock-up/knock-back/suppression/suspension on VOODOO turns into a 70% slow to the linked Champion (same duration, linked champion does not get stacks, so no 70% slow on top of 70% slow) Any Snare/Entangle on VOODOO turns into a 40% slow to the linked Champion

Q - Range: 1000 Speed: 2000 Cost: 60 mana-ish cooldown: 20/18/16/12/10s

Linear skill-shot only hits champions

If an enemy champion is hit, Deal 40 / 70 / 100 / 130 / 160 (+ 30% AP) magic damage and Temporarily steal all buffs and debuffs from the champion for 2 seconds, at which time all buffs and debuffs return to the target hit. (death prevents return of any time based buff/debuff, permanent buffs/debuffs are returned regardless (Anivia egg))

If an allied champion is hit, Steal all debuffs from them and all debuffs they take for the next 2 seconds are instead applied to you, if a linked champion is hit, they are immune to transferred movement debuffs due to the link (see passive)

W - Range: 200 Cost: 15 mana Cooldown: 12/10/10/8/8s

Directional linear dash with variable range up to a maximum of 200 + (30 x number of debuffs on VOODOO), Dash removes all slows on VOODOO (and thus any slows on linked champion via VOODOO's innate)

E - Range: 750 Cost 70/65/60/55/50 mana Cooldown: 18s

Passive (always active) VOODOO deals +2/4/6/8/10% Damage, does not apply to true damage

Active Target Champion gains a shield for 100 / 125 / 150 / 175 / 200 (+ 5% Maximum hp)(+ 50% armor)(+ 50% Magic Resist), Shield lasts for up to 5 seconds

R - Range: 1200 (cast) 750 (around you) Cost: 100 mana cooldown: 65/50/40

VOODOO channels for 1 second, while channeling VOODOO is slowed by 20%, if he is interrupted during this time the skill goes on a 5 second cooldown, and the mana is refunded

Places a copy of target champions buffs (at the time VOODOO began channeling) on all allied champions in a 750 range for (8 - number of champions in range that can apply the benefit) seconds, any buff that would run out before the duration of this skill is over will disappear, some buffs are immune to copy (trynd ult, kayle ult, VOODOO Passive, Fiddles ult) All Copied buffs use the stats of the champion it is on.
