Thanks everyone. I actually bought that aeon guide and did everything it said to use for sentinel which really helped. Also I tried something else which I will be using a lot more. When I went into the dungeon with t-7 (he is required to be in this particular mission), I summoned Kira, she does a ton more damage. With her, I cleared that place out with no problems and the boss was a joke. Then when I beat him I summoned back t-7 to finish the mission. =) worked like a charm.
Does anyone make medium armor here? I have credits to spend. The galactic trade market is tricky for me. Some days its filled with goods and the next its completely empty. Until I learn how to customize my own armor i am willing to buy. I just hate capes and everyone for some reason has to have a jedi in a cape or a robe. I am not really a fan. I just want battle armor.
Thanks everyone,
