Ashoka Tano

She's very useful in GW, because she's sustainable. Despite of being an attacker, her self-healing abililty is usually enough to keep her alive, so you won't need to use you healer very often (=more overall dmg output).

I will be curious how the new gears will help her.

Actually, if you are avare of modding her, you can find a set of mods which makes her very viable. FYI:

• critical dmg set (4 mods)
  
• triangle primary: critical dmg or critical chance, depends on the leader you use. With JKA: chance
  
• arrow: critical avoidance (if she suffers a critical hit, she will loose her ability)
  
• put as much as health on her as you can, to get more HP healed
  

Put her in the GW with JKA lead and a proper Jedi team, and thank me later.
