TANK REWORK - NUNU concepts (feel free to comment)

i have a cool concept for nunu rework, since riot doesnt like boring no skill chams, lets make nunu more interactive with his yeti. Q:The yeti except just eating a minions grants a buff, can also be used anytime to grant nunu a snowball ( can store up to 3 ) for his e W: grants nearby allies attackspeed and applies a slow effect on nearby enemies (well i mean its a roar, its a yeti, its snow. why the fuck not) E:the yeti throws a snowball on a straight line (stores up by q or passively stores), explodes when hit the first enemy, then apply a small aoe slow to nearby targets and dealt 33% of the damage. OK, now lets talk about the big idea about his whole kit. R: Yeti enrages and leave nunu (summoning concept) but you cant control it, it scales off your ad, everytime the yeti hits it applies a slow effect on the enemy (scales off ap), yeti attacks apply a stack for allies (including nunu) , when it reaches 10 stacks on that target yeti roars and apply an AOE effect and fear minions, also grant itself a 50% move speed buff and 30% attack speed buff. while nunu is not on the yeti it has the same ability as Q and E , grabbing snowballs and throw them, but not allowed to auto attack. yeti has its own healthbar. when yeti dies it goes back to nunu but apply a exhaust buff ( 30% damage deducted, slow etc (basically exhaust). OK YOU MIGHT THINK THIS IS OP. LETS TALK ABOUT THE PASSIVE. Passive : when nunu attacks on hit an enemy champion with a skillshot, OR GET HIT BY AN ENEMY grants yeti a anger meter. when it reaches the max R is active. when nunu is on his yeti it gives him extra 20 armor and mr. i personallly think this is gonna be awesome and hope you guys can leave a comment on it :D
