I was a fairly new Padawan when CU went live, with Master Rifleman/Master Fencer/and TK meditate tree. It was a nice compliment to Jedi before CU.
One problem with having elite combat proffs along with Padawan, you're level is way higher than you can kill with a saber. The creatures you can kill with a saber give 1 xp.
I had to respec down below lvl 40 before I could kill anything solo. I added some Doc for self buffs, healing, and some Ranger for the camo, tracking, traps, and increased terrain negotiation.
