What's the deal with the Ice King constantly being "Fite me"? Not sure about you but it's got to be the most frequent RE I've seen.
because you can only battle him by clicking through the random event link. so this helps for battlers who want to fight him five times for the boss loot drops.
in order to get all the wins you need on this guy to get the super-valuable mod crystals, mage amulets, and tomes, you need to fight him a LOT. This is especially true for a user like me who has a whole army of trained pets and a well-equipped Armory.
However, if it wasn't the Ice King challenger RE that some users didn't like because they don't battle or don't have pets strong enough yet, it'd still be something else. It used to be the Bumbii of the Bumbus Queen offering to you that you could convert one of your pets that was the most common RE that folks would complain about.
