I want a Murky!

So, with Heroes of the Storm recently entering beta, and it being really cool with unique hero concepts, and League also trying to come up with unique ideas... why not rip HotS off, with one of their more gimmicky and memorable Heroes?

Murky is a hero who, at first glance, is really weak. A hero with pitiable attack damage and tiny health, but his trait lets him place an egg that lets him respawn in the middle of the map, he's worth far less XP than any other Hero, and he has an ability that not only makes him invulnerable (while still able to move), but at higher ranks this ability can also heal him almost to full!

Right now, he's the weakest hero in the game, to the point where people complain when others pick him, but there are solid plays. One build for Murky lets you exploit his invulnerability time and the huge damage on the rank 20 variation of his second Heroic in order to win 1v1s against foes who are nowhere near as squishy as you. He's also built for sieging, able to easily clear minion waves with his strong AoE.

I kinda think LoL should make a hero with a similar concept; weak and squishy at first glance, but persistent and very hard to "truly" kill.
