Need Help after a long break

Sagefire

Hello,

after a 6 month break I decided to rejoin this game...because I invested a good amount at this game I don't want to restart. So now I have the problem that I'm lvl 80 and everyone else is on 85...it will take a while to catch up . I asked a friend and he said that it will take me at least 1 month to get to lvl 85..is that right?

On which character should I focus on? I saw that some top #10 players on my server are playing Maul (L) with Kylo and Savage. I already have Kylo and Savage at 7* max gear. Are they useful right now, or only when pared with Maul and lvl 85 maxed out?

I want to start farming Maul but that will take a while...should I buy the 4* pack to get him a little bit faster? - can I use him at 4*/5*?

Currenty my arena team is: Anakin (L) - Rey (nobody uses Rey anymore :O cant belive it xD) - QGJ - Kylo and RG.

Are biggs and Antilles still a thing so that I should farm them? or will they disappear with the new sith meta?

thanks
