I am in the process right now of making everyone on my team into a Transmute master for the epic gems transmutes every 20hrs and a JC for the JC daily. The way I see it, 10 mins of time should get me at least 4 epic gems and 4 Dragon's Eye per day. Assuming xmute mastery didnt ever proc. Sounds pretty good to me. The downside will be the no disenchanting for me . But I'll have enough gold I"ll be able to pay an enchanter to just tag along lol. If I felt so inclined.
