Impatient speedrunners stink, but the autotranslator is great!
My experience is that this is extremely common, and that impatient speedrunners will frequently go beyond simply skipping rooms with coffers into actively abusing new players by trying to bully them into skipping cutscenes, then rushing ahead and eventually locking them out of the boss battles. Without ilevel sync or some other mechanism to prevent it, overgeared players are able to lock the healers (and anyone else) out of boss arenas without dying. This isn't nice, but people do it anyway. :(
Echoing what Asheilin said, the autotranslator is a great feature for communicating with people who speak another language!! I wish I got the chance to use it more often because it isn't needed as much on the NA servers, but it's a wonderful thing for a game to bring people together from all over the world. :)
