MK5 stun gun salvage

I need 8100 of the Salvage just for my current characters I am sure it will be more once I get Revan, Traya and Probe Droid. They are ridiculously hard to get.They drop in Guild Store, Guild Event Store and Shard Shop only once a week maybe twice. They appear in shipments but are so expensive over 1200 crystal it is a bad use of crystals. If they gave us a way over converting MK4 salvage to MK5 it would not e so bad since I have around 4000 of those kicking around. I can understand having to be a whale in order to get characters before everyone else but you should not have to be a whale just to gear up characters you spent so long farming. I try to give the game some $$ each year to support it but being married with 2 kids in school I have priorities and if I am going to start having to put big $$ into the game just to play I may just end up quitting like some of our guild mates. All this and I do not even care about Arena and PVP I just like playing the events and collecting everyone and leveling them up.
