[Dumb Ideas] Zac's Kit

Zac's kit is alright considering the Q & E but his passive, W and R seem to be very weak. His passive is very useful but although every passive needs a weakness this one is doubled. His passive allows him to revive but at a very slow rate. He bursts into 4 small blobs that try to get back together. But the rate at which each is trying to get back to Zac seems unfair and as if you guys made it so the enemy will have enough time to finish him. Now, if someone gets on here and starts bad mouthing this saying "his passive is very strong giving each blob 1/4 of his HP," then I will tell you that 1/4 of 2000 is only 500 HP. And yes trying to get each one is hard but Riot needs to cut Zac a little slack. His Q is fine with the amount of damage and health needed to preform this ability. But his W does not need so much to activate. Sure it deals a good amount late game but it will only deal like 4 or 5% at early which not that much at all. His E, like I said, is fine allowing the player to travel a long distance, dealing a stun, and dealing good damage. But that ultimate is not that much of a ultimate like it use to be. It shouldn't be targetable. His ultimate deals a lot of good damage but all that comes with this ultimate is 1 stun per champion. His ultimate reminds me of Fiora's only hers is not targetable at all. All I'm saying is for Zac to only be targetable by turrents, baron, and dragon. Champions, monsters, and minions should not be able to hurt Zac.
