My suggestion is to change the requirements for the t6 repaired dragon scales to require - lv100 adventure school, and a lv100 craft school (either dcrys, LSH or dcraft).
I'm going to make a comparison between bipeds and dragons. Please bare with me, and keep in mind that I hope this is taken as a comparison, not a one vs. other. I merely think that the effort a biped needs to give in order to wear t6 is an appropriate amount of effort, and think dragons should be the same way.
Biped requirement: 105 rating. A lv100 school and a 70.
Dragon - Ancient (which is, 100 adventure, 30 craft).
Number wise, there is a difference of 40 between the two. Effort wise, dragons have far less that they need to do in order to reach t6 than a biped.
In wandering the /who lists over the years, I've seen a significant amount of dragons who are a lv100 ancient (I think you could go lv90 if you were -really- lazy about it, but can't confirm), and then they're got lv30 or 40 craft. It's a straight, easy journey to Ancient with minimal craft effort. At ancient however, they wouldn't be able to craft t5 scales, much less t6.
In short - I feel that requiring only ancient to wear t6 scales is too easy. At the laziest, being able to wear t6 scales doesn't require much effort at all. 100/100 would be a more accurate representation of effort expanded than just requiring ancient status. The ARoP is a very nice flavor quest, but does not accurately represent character progression. Lastly, there are some who will never ascend to ancient. Not many, but I thought I'd throw this in there.
