Which legendary lord/race do you have a personal issue with?

I read a post from a day ago from someone venting about everyone's favorite Prince and elector, and every time I watch a vid by Zerkovich he hates on elves so it got me thinking, which LL or race do you have a personal issue/vendetta with no matter who you play?

I really like Bretonnia/Kislev using the old world mod and Cathay on regular map so for me it's the Skaven. I don't care who I play, what mods or which faction, those little rat bastards do my nut in.

On old world they turn into a power house every time and are a nightmare to fight because they're everywhere. As Cathay I inevitably end up playing wack-o-rat all over the bloody desert or mountains as the same army springs up in a different location every turn only missing a 'bazinga' to elevate them to 'sheldon in a ball pit' levels of annoying.

So who is it you despise in this game and why?
