So yeah, I'm not sure what it is with people playing Rogues and being afraid to get their hands dirty.
There was a massive, overwhelming change in D&D that took place around 4E, where you started getting back all of your HP every day and even had resources with which to heal yourself
during combat
without using any other party resources. Ever since that happened, it was considered reasonable - even
encouraged - to spread the incoming damage around a little. You were
supposed to get hit.
In earlier versions of the game, HP recovered slowly, and the cleric's spells were a resource which needed to sustain the whole party (if you even
had a cleric in the party). You absolutely did
not want to take any damage if you could possibly avoid it.
It's a tough habit to break, because the idea that it's
okay for someone to hit you with an axe - when you're not even wearing much armor - is
amazingly counterintuitive. Instead of calling those people
bad players, you could say that they're
good role-players... who simply haven't gotten the note that they're playing demi-gods capable of shrugging off multiple axe blows.
