How often do you actually solo on a combat class at 50 though, apart from doing achievements?

And I agree with an earlier post; for the most part, jobs can do it just as well as classes at 50. As your leveling up, classes are a little better because of their flexibility, but this is high level gear, so it seems pointless. Again, I haven't seen the stats on it, but I can't imagine it's going to be so great that it trumps AF or Darklight with multiple melds AND with no access to job abilities that the classes still outperform their job counterparts.
