I kind of agree.

Personally, at least when it comes to casual stuff, the variety I get comes from running things on different jobs. I just did a Bunker as BRD for the first time when I haven't touched the job since leveling it months ago and even though the fights are something I'm very familiar with I enjoyed doing them while trying to reign in a new skillset. I also found a few places for Paen which was nice.

Personally I also find fun in chasing numbers. It might not be everyone's cup of tea but after a while that's all that keeps me going on some EX fights and stuff when I want the mount like - okay, I know the fight, but this time I'm going to do X and see if I can eek out another percentage.
