Ardent Censer idea
passively gathers up to 3 stacks from which one will be consumed when casting a shield or a heal increasing its effectiveness by 25 (+5% targets missing health) and giving a 75% attack speed boost for 3 attacks. Attack speed not applied to self. Aoe shields/heals apply the buff prioritizing low health allied champions. A single stack generates in 30 seconds.
This would replace the current passive obviously.
#Why? I think Ardent cencer is quite bland. Giving it an interesting passive would make it a bit more interesting item.
