Ideal FO team for arena

depending on how things look for jtr, still got like 180 shards on kru and kylo before a fox. got phasma 7* as backup plan for bb8, fost farm is sort of a slow deal, and i started kind of late, now doing some off farming on rey scavenger on ship node when i can. i cant really level much atm anyway. but if it works well in a new shard like ikky said i guess i should not be worried to much and just keep leveling and gearing, he they fit in the ship also. i can reach down to like 50, at first, at around 100 now but teams got quite a bit more powerlevel 10/15k + and i seem to derank quite quickly for now, and if i get bad rng i cant win over the really high power teams. but im doing quite alrigth in ships so not doing better in arena for now dont worry me too much. more concerned about getting any good legendary heroes atm, as ive missed out on just about every event so far cause i didnt want to lvl phoenix instead lol. tbh i didnt know shit about the game at first i just started leveling something, tried to farm jedi team, sith team, then swapped to farming rebels for palp for my sith team, then decided for FO, cry inside for missing palp, but decided to stick with it for once as kru and fapsma was one of my better heroes i for some reason had farmed. ppl will have thrawns, not many do i know just one guy in my shard and he is in my alliance, palps, r2d2s ++ but if im lucky i migth just get JTR, but seeing here how ppl say FO is that viable to contest teams with legendary heroes makes me wonder. i definately would need that fox, cause my team atm seems a bit too many paper soldiers. foo and fotp, but fotp serves me well in ships also.
