IMHO it's more that they've removed the best data discs that allowed us to be creative to complete feats and sectors, and now it's mostly having your legendary/GLs teams drag along the unit of the conquest cycle like a bad escort quest and hoping that unit doesn't die as even at decent relic levels, Batcher and the new BB clones can't complete a single battle on their own in sector 4, so it's really 'babysit Batcher with Rey or Kenobi 15 times'
Really poor game design.
We've also had the same enemy teams for over a year now. Please add some variety.
