Mog the Punching Bag Champion Idea

One of my friends and I came up with an idea after Kaisa was released keeping with the adaptive theme. Here it is:

4 Way Passive: Passive 1 : Annoyance. The longer the match is the more health and objective damage this champ does scaling with +50% every 15 minutes up to a +200% cap. Passive 2 : Who needs Warmogs? This champion has a health scaling of 125% from any item that boosts health, but any bonus damage stats from items will be negated by 70% Passive 3 : Weighed Down. As the game progresses, This champion looses 10% speed every 15 minutes capping at -40%, however, boots of swiftness and other tenacity items effects are boosted by +10% Passive 4 : Super Villain! The enemy with the highest KDA does bonus percent true damage based on the amount of tenacity MOG has Maxing at 10%

Ability Ideas: Q: Shoots a splitting missile from her armour that does more damage the less health Mog has maxing out at 10% health. Pierces enemies, The missiles will slow the target by percent move speed based on how far they are away from Mog. The slow is enhanced greater around midway of the shot travel time then decreases. W: Puts up a huge barrier that lasts longer the more health mog has maxing out at 10seconds at 100% HP E: Increases targeted ally Tenacity and MR or Armour Based on the stat that Mog is not building for. If Mog Is only building HP, This ability Doesn't increase MR and Armour but instead increases speed and effect lasts longer the less MR and Armour she has; WHILE Temporarily increasing her own stats by a quarter the amount given to ally. R: (Channel) Shreds health down to 25% of remaining health and gains adaptive damage equal to 1/4 of the health shred, but lowers attack speed by .6/.45/.35 of base.

I'm skeptical on the idea of a four way passive, but that's one way we thought of to balance her. Give me your thoughts! Would you like to see something like this in-game? How would you alter her?
