It's not that I'm saying I couldn't make an interesting taunt, it's more I'm not sure how to give one to this Rammus. I mean... he's not all that threatening, visually. He's not innately magical. He's just... a rock.

... and while writing that I instantly thought that maybe he could taunt all non-champions damaged by his ultimate, allowing him to take aggro (including from turrets). Saying that, though, I think I'd rather promote my Jungle Patience rip-off Threat system for towers where different actions generate different Threat and the turret always attacks the most threatening enemy (and then have Rammus' ultimate generate extra Threat, still).
