Frozen Mallet.
Rant post, beware
This item is so uninteractive. 30% slow is a LOT. But, it's a niche item and I don't think it should be removed. The current passive is however so crippling if you don't have a dash and are melee (which is probably 1 champion out of 5, 6?). Excuse me if I'm wrong, but this item was designed especially for melees who have trouble sticking to their target (the passive has a ranged and melee restrictions). It sadly is only used by ranged champions.
Its AP counterpart, Rylai, has counterplay and is much more healthy. You can dodge (most) spells, but you can't dodge AA's. It's a guaranteed slow, turns into a kill if you happened to be in range of the holder.
That being said, the item isn't even strong! It's just so toxic to play against. I could pick Nasus into Pantheon and not swear once. Every time I play against a Frozen Mallet I wanna hang myself. I generally have fun in League, I am friendly in-game. When I play against a Frozen Mallet I'm not the same person. I just spent around 30 mins wanting to leave the game at every second. I'll end this post with an highlight of my most recent game, where I completely lost my mind.

What are your thoughts about this item? I'd propose to buff the stats and reduce the slow, or something similar.
