i play for about 2 years and got my vader,biggs,tfp,fotfp, thrawn all to g12 for fleet arena working on reaper and pilots still but vader on 6* after over 2 years is just low. Even i played totally casual 1st year w/o even looking much at synergies.
And tbh i love the change finally i got chance to get in to top 5 with my fleet due to not having reaper, shore and DT maxed out on stars and gear to be competitive in top 10 of my shard.
For the record i am full FTP didn't spend single $ on game but you do need to have some strategy and farm some stuff to be competitive in top ranks in both arena's.
