Please just remove datacrons from the game. They absolutely blow!
Remember when Blizzard introduced the auction house in Diablo 3, then eventually canned it because it upended the entire point of the game? Well, replace Blizzard, auction house and Diablo 3 with CG, datacrons and swgoh.
Datacrons negate the gameplay loop of gearing/relic-ing your characters for three reasons: they're insanely OP so trivialize prior gear investment, they're temporary in nature which makes them unsatisfying, and they break the hard-fought balance of the game.
They could have been used effectively to boost C-level teams (ie Phoenix) for some fun novelty, or in a more modest boost to non-GL teams, but as they are they're broken. They were broken before the recent "improvements", and they're broken after too.
