Yeah, he's SOO safe and deals a crap ton of damage with Muraforce. You can even build him a little tankier with Blue Ez and still deal a fuckton of damage. Then you throw in a Botrk, Shiv, PD, BT, and/or IE in there, and you get shit tons of damage at once.
Actually, what are you guys' thoughts on Shiv on Ez? I've only built PD on him before because it makes him auto faster, but I think Shiv might work because it will give him wave clear apart from his ult and even more damage on him poke. It sounds like it would work in my head.
