4* ATF

Depends on your shard and your rank in it. And her gear level & mods. I use her with my 2nd account in an R1 squad at 5* and just got her up to G9 a few minutes ago. Been hanging around 50. Can't say if she effected my rank because I just changed squads entirely from droids and they couldn't get me higher than 100 or so any more. Time will tell if I keep her in there or drop in Bistan or Bhodi.

probly not if you want to be in the top 100 in arena, she really needs a team around her to put up buffs so she can do huge damage, like general kenobi and zYoda on battle meditation, fAhsoka isnt gonna make a huge difference by herself...

Yeah, I was already building the R1 squad just because they're fun. fAhsoka came along and just happened to fit in nicely since it's a buff-happy squad.
