Which rotating game mode do you dislike the most?

You all know what it is, every patch they put out a random game mode (or an event game mode like Blood Moon Hunt, Poro King etc.) from Ascension to AR URF. I would like to know which game mode you dislike and wouldn't even wanna play and explain to us why you dislike it. I really dislike the Poro King game mode not only is it on the ARAM map but its also extremely annoying how spammable the Poro Snax are, having to dodge a lot of projectiles back to back is really infuriating to me. Its cool and all that I can pick whichever champion I want but the people who play this game mode a lot pick the most tryhard and annoying champions, most of em being skillshot based champions.
