Cacoadragoon, to answer your question you are able to do 4-5 crafting 49 pure essence (98 nature runes if you are 91+ RC). I best time to repair is 4-5 runs after the first degrade of giant pouches and you still runecraft the max amount per run 3 pouching.
And for repairing I believe you still use abyss, however there is a new way, which you can use NPC contact spell to dark mage to repair your pouches.
Hope this helps.
