1st, to the OP. I agree with you to a certain extent. Dealing with PUGs sometimes you wish you have those extra ablities because ppl faceroll through CT, I know I have. I think having those extra utilites would be helpful for a group that is very new to content would be benefical. I see what you are trying to say and do and I think its ok.

But, say you as ARN get into a group that is very good. I would be frustrated seeing you trying to do extra buffs and heals that is not needed, when healing and buffs are covered then you need to focus soley on DPS. The problem that I see with your approach is if you are using DF you won't know what type of group you get. Personally I'm goign to suggest to my FC of doing HM primals, CT, and some other stuff as classes instead of jobs. I know our FC can easily get a group of 8 ready to do it. it would be a vanity project to have fun and not take the game so serious, but we would never do that if we were in new content trying to achive something.
