Support with new mechanics (well kinda new mechanics)

So when Riot created Azir and him summoning a tower as a passive they said in his video that they are looking for new mechanics for heroes, well this concept I had doesn't have completely unique mechanics but it hasn't been done yet and rather than having champs that a damaging ability with some effect i thought of bringing the brush to a character.

So Brokai because he would be coming from maokai's treeline excuse the pun basically has the ability to use the brush to his advantage. So his passive would be spawning the brush behind him as he walked for 3 secs and then it would decay with that allied units in a brush and his passive would make him in the brush but visible. would get 20% of his armour, magic resist and healing

"Q" First activation reveals all enemies in the brush in a 1000/1100/1200/1300/1400/1500 range radius. Second activation stuns all enemies in the brush in a 700 radius of brokai.

"W" Pulls a enemy champion towards you, allies can also be grabbed and deals magic damage to enemies or shields a ally for 2 seconds

"E" Creates a Brush wall almost like anivia or karthus, this wall blocks the line of sight of enemies but does not block the vision of allies.

"R" Creates random patches of brush in a 750 Radius, the brush has vision inside for allies, after 5 seconds the brush will colapse and deal damage to enemy champions and heal allies standing inside his ulti brush

Well thanks guys for reading this, I know alot of people will criticize this idea but it just popped into my head and thought i would post it
