Tie Fighter does the Foresight evasion count as a dodge then?

It is doubled. So 50%TM gain on a dodge for Executrix or Chimera. That's the battle right there. I'm not sure the prevalence of Biggs/Vader/TFP is due to the fact that it's still the best period. It may just be the best available - everyone had invested in them pretty heavily pre-2.0 so of course they're going to still be strong. Not a lot of people spending valuable resources on Geonosians early on.
