I love #DungeonWorld, but I’ve decided I don’t like the RAW Thief class much. The poison-related moves are so central the Thief seems to play more like I recollect 1e Assassins playing than old-school Thieves. This conclusion comes after playing a Thief in one session and GMing Thieves (by different players) in two more.
Maybe a tweaked Thief will be my first effort at a new(ish) class.
