1.) ok it is true t3 disciple's exist on garden of the gods patch but i meant that asking around on live server no one uses it anymore (the word trash was mentioned a lot) and threads were abundant about the issues since a while ago, basically even with T3 disciple which is incredibly expensive btw on PVP you are 1 shot sure kill and in PVE is too weak to farm GoG for most classes with some exceptions (i think mostly archers were mentioned).That is not true for Disciple's gear. It still continues to get additional tiers afterwards and act as an alternative gear source.
As for converting gear into supply kits if such a change was made. It would only allow for converting back to what it was made with. You would not be able to convert Library items into kits that can feed Hiram
2.) that would be fair, at least would be useful to feed some nory accesories at least
