Alright so I just got my hands on some 242 mods and I'm trying to apply the armoring mod into my belt, but I keep getting an error message saying "This modification is restricted to a specific piece of equipment and is not valid for target item" How can this be if I removed it from that previous piece of armor I had it in?

Alright so I'm on my second playthrough as a Sith Sorcerer and I've noticed whilst playing PVP that I really cannot contend with a lot of players on here. Especially not the Sith Assassins who seem to have way more health than I do and their moves destroy 1/4th of my health in literally one attack. So my question is, what skill tree should I commit to on my Sorcerer? Also, what abilities should I focus on getting/using?
