Ever since wave6 dropped I've always felt the Imps were lacking something in that 30 point area and they could really enjoy something meant for dealing some marginal damage on a tiny frame. Basically, it feels like Hammerheads would have been a great addition for imperials, and possibly that the Quasar would have filled a nice niche for Rebels.
Anyway, with wave7 coming out, Rebels still seem to need more medium base ships. And Imperials could use a 30-40 point combatant type ship. Gozantis really don't attack well unless you make a gimmick list out of it.
Oh, and Imperials really seem to need better/more variations of bombers without Rogue. The choices are basically Tie Bomber (fully bomber, but soaking up tons of squadron activation requirements) or Tie Defenders (which are poor bomber value for their cost).
