In the recent dengeki interview I think it was (and there was a famitsu one too so I don't remember, yoshi's been busy), it was seemed to say that overall, vitality isnt going to give as large dps performance as strength does now.

So yes nerf it is...yup

Not a big one though, if the translations are correct.

I'm not really sure where the feeling is coming from that I see: "Tanks need to carry all the bad players!" Aren't "bad players" equally divided out to all of the various roles? I'm not aware of tanks being made of magic in such that they just in general play better than the rest or something. Maybe tanks are just somewhat above suspicion? I know in the past, not many wanted to play tank, so the party didn't dare talk back to them or criticize them. Is that really still the case? I know people sometimes still decide to play tank because they still think that is the case though.... "Oh, I got in trouble a lot when i dpsed.... I know! I'll be a tank, they will have to worship me!" :/
