Cho does too much of everything except mobility

Honestly this champion has been one of the strongest champs so far. He does almost everything... He becomes tanky naturally, massive sustain in lane (hp and mana), knock up AND SILENCE that both does good damage, has good auto attack because of his E, and not to mention HE HAS A TRUE DAMAGE ULT that can kill any champion if hes building AP. I think he needs a nerf on one of these area. Take away his silence, or lower his sustain (lower hp sustain and no mana sustain), true damage ulti to ONLY monsters and change it to magic damage so we can build against it. Only bad thing about Chogath is that he has no mobility what so ever but he has a aoe stun up that last almost 2 seconds and a silence so you can do much about him not to mention that hes tanky. And the fact that he has long cooldown but can be negated if he builds cdr plus blue buff.

He's too good atm and particularly unkillable by the mid game if hes smart and doesnt die early game by ganks which is sometimes hard if he plays really safe. And even then hes still hard to kill mid game when hes doing bad (saying if the cho gath player is smart). He's too good atm imo.
