Basically i'm currently lvl 42 (BH) and just completed Belsavis, however my next planet is Voss which states the suggested lvl is 44. Now I can quest on Voss despite missions being orange and mobs pretty tough. I can't help but feel I have missed a Bonus Series somewhere... Currently the only planets I never received a bonus series from are Alderaan, Quesh, Hoth & Belsavis.
