Evelynns Rework Idea

When I heard Riot thinking about an Evelynn rework, I thought about her passive. I think her passive shouldn't change, I love the Invisibility, but I hate how its used. I think per passive should be when Evelynn is behind a enemy she becomes stealth, boosted one of her ability or not depending what the new ability will be, but I think it should really be similar. So please listen to this.
