An example of a half-done sector. It doesn't even get DSEs! And with the advent of PvE queues, it's basically dead.
They should probably put the used planets into Gamma Orionis and replace Pelia with a Fluidic Space Exploration Sector Block (but with DSEs perhaps?)
Of course, we'd need more than the Undine then in Fluidic Space, otherwise it would become boring fast. (I mean, faster than usual). But add some decent endgame gear or Dilithium Rewards to it, and you got a well frequented sector block.
