It'd have to be the RainMaker. It's leagues stronger than every other weapon that can naturally drop and even every other event weapon, it's ranged, and it has otherwise impossible hero health to boot. It seems to be universally useful against every boss, and its status as incredibly useful has been preserved by no CDT event ever distributing any strong apprentice DPS weapon, let alone one that remotely compares to this beast. Veterans stereotype people who are under-geared as complaining about not having a RainMaker specifically; it's the poster boy item when it comes to that divide, for a reason.
