Nope, it was 10 levels below the optimal rank to craft, a lot of people seemed to be confused about that. That being said they did lower the difficulty of several items during the update so people were spontaneously able to repair them, so it is understandable why this would be misunderstood. As a kind of proof I have been repairing my Bronze Solerrets since ARM R5 when they are optimal rank 27 to wear.
See, when I made my own Bronze Sollerets
way before the patches and changes, back near launch, I was unable to fix them even at armorer15. It wasn't until armorer17 (27-10) that I could fix them.
If repairs are now based on rank needed to craft, then I can clearly understand why I can fix my brand-- it takes tanner25 or so to make 'em.
I'll try to mess around with more items then and see what I can figure out. My armorer19 shouldn't be able to fix my lantern shield (Optimal rank 34, rank to synth 40) nor would my alchemist 23 fix my bee spatha (Optimal rank 36, rank to synth 36).
