@ the general discussion
I agree JJ needs some love, even if at this stage in development it's just tweaking piety gain or costs.
Rogue is OK in my book... on the powerful side in more situations than most classes but still fun and interesting to play.
@Q3 - if you're willing to restart a few times to get a solid start I think most 2nd/3rd tier classes can find something useful to leverage on dungeons they're good at (cf purist crusader parched DI run), not sure that's just a problem with the rogue. The rogue's exaggerated stats just make it more obvious. Rogue is perhaps also stronger on Vicious dungeons (as long as he can make up the HP) just because the very high damage makes it much easier to clear monsters.
