Whats with the cho'gath bans

He's banned because people like to play assassins, and he counters them.

but they build ap tank or full ap, not recently have i seen tank cho.

cho is more recently been building mage. And you can't get close to him because Feast will do tons of TRUE damage. Can nearly burst down anyone who gets too close, or caught out in his rupture.

He can still be kited. But as it stands, his Damage build does better for zoning than his tank build. And for that, people call him OP.

if cho gath bulids ap he needs to land his skillshot

Full ap is definitely what makes him scary, 500 ap gives him +850 magic damage on his aoe QW combo letting him do around 1200 damage to squishy targets. The 500 ap also means his feast is doing 1k true damage, and as a cho main I love ulting carries for half of their health.

his ult still does the same amount of damage regardless of building tank or straight ap true damage

He was played in the LCS.

You do know that he can flash in and 100-0 you in like 2 seconds right?

then he silences you, uses q, and eats you and you die while being full tank

because people tend to not want to be eaten.
