I think the difference between "Disruptors" and actual Tanks is that Tanks can... ya know... tank.

Also, every one of the Disruptors creates areas of denial. For example, Anivia can wall off areas or use her ult to control where the opponent goes, while Heimerdinger and Zyra can create gun nests (or "fun boxes" if they're yours) where any enemy that enters gets shredded.

Meanwhile, none of the Disruptors really scales with defensive stats, meaning they're often squish as hell.
