Help me. I suck at GOH.

So I have a reasonable number of character but my team is utter trash. What should I work on to turn it into something decent? Character list in following links:

As you can see I had no idea what was going on.

Keep Lumi and Luke, farm QGJ, Dooku and Kylo

Unlocking characters doesn't mean nothing. You have to lvl them and gear them to do something. Put your effort in a low number of characters (gears and stars), plan a squad to arena and raids. Spreading your attention to a huge number of toons at the same time is a bad idea.

Star and gear up Dooku,QGJ,Rey, SThan and RG...go for Daka when you have QGJ at 7*
Like Kit_Fisto said...focus on having 1 team for Arena and max them ...and make sure first you don't have any trouble in GW ,if you have put your priority there.
Then plan for raid teams...Cpt. Phasma is a great Leader for Raids

QGJ, Dooku, Phasma, Daka, RG, Luminara, ST han... you have a lot of good ones, just need to pick out a select 5 or 6 and go to town on them

Mol_Eliza12

Definitely go for Rey. She has incredible damage. Keep starring her up!
