First of all instant jumping to lvl 65....I had that opportunity as well but I did not grab it
You will lose on so much if you jump a head.
- The story
- Leveling
- Background of your character.
- Dark side light side choices.
And as Mubrak said ''Most of the cartel market items are in random packs'' that's more then true
You have a chance of getting the items that you want but most of it is scrap....(My personal experience)
Do us a favor start from scrap, You will enjoy it more !
