Whom should I give the mk5 cec fusion furnace?

Furnaces are very cost effective to buy for crystals - considering crafting with salvage requires 50x MK6 hyposyringes (1400 cost) and 20x MK3 Holo Projectors (300 cost). That's not even counting the 50 salvage from raids. I would say given how many characters need the MK5 Furnace (it's a lot - BobaFett needs 3x all by himself), if you have crystals to spare, buying them in shipments when you see them is never a bad idea.
