Well in regards to the rebel themepark I completed the parts on Corellia quite a while ago, and i basically got crap. SO it looks like the loot is better... And i did those solo, I think I was at that time just 0142 in TKA, and 4430 in Doc, so a Master Carbineer should be able to solo them, but who knows... I myself never completed the Jabba missions as all i was getting was crap, I got as far as the first mission for Bib Fortuna and stopped, im curious if the loot there is any better...
