Neeko vs Amumu

After seeing Neeko's kit, i am afraid she will outshine Amumu with her R. I get that they're both very different characters, when you look at the rest of their kit, but one thing (Besides Amumus BANDAGE) Amumu is really known for is his (oh so good) ultimate. Yes, they both have their own ways of executing the ultimate, but I think that Neeko is overall superior. Cannot be targeted before cast and (After using one of her abilities, I think that's E) her ultimate cannot be seen by the enemy player? What are your ideas? What do you think?

rework next?
