Padme health and speed with health primaries, speed arrow. Triangle can be health or crit damage primary
Ani and ahsoka, cc/cd
Gk can be messed around with, depends if you want him fast, or just ridiculously tanky, I think I've got tenacity, health and def sets on mine.
3po, not sure but gotta assume health and speed since other stats won't really help him much. I don't have 3po yet either so I can either use my g11+5 CWC, he can get to 20+ stacks of courage quick and deal serious damage, or my g11z r2d2. Gmy works unless you need him with revan as I do
