They don't design champs with their functionality for other maps in mind. At best they've taken to nerfing damage and utilities (which is what he was referring too).

His overeffectiveness on Twisted Treeline due to the area and himself having a similiar color scheme is mostly accidental but isn't anything they would care to fix because it's not a problem on other maps and espescially Summoner's Rift.
