It wouldn't help as people somehow pass the solo instances for their jobs and are still clueless on not only how to play it, but also what some things are like stack markers. Or just simply don't care because they simply only want to put in the minimal effort. I mean the hall of the novice and the gld lv 15 fight both at least tell a tank hey please use these skills, but you still end up with fairly craptastic tanks at lv 80, We've asked for years for other higher level training simulators and so far Yoshida has been very iffy on them.
