New player here, advice appreciated

Right now wedge and Biggs make up a dominant team. I use them in conjunction with Leia and Stormtrooper Han. I am by no means at the top of the Arena but this team works pretty well for now. The reason people say 2 farm Akbar is because he will work so well in conjunction with Leia. Apparently his special Talent gives her the ability to almost constantly stealth. I did not raise Akbar very high myself. Right now I just stick in a fourth member like Vader. Vader is not easily farmed unless you use Guild tokens or Fleet shipments. Boba Fett got an excellent rework and Sun fac is one of the highest-rated tanks. If I were starting again right now I would just concentrate on Biggs and wedge and build around them with Stormtrooper Han but this is my opinion.
