Your ideas have merit. But, we want to reduce the amount of time in game. CG is pumping it up excessively, especially in TB at this point. (My guild is running 5 planets in Phase 4 and 5 at this point.)
They need to do some upgrades and updating to TW and GAC, but they're probably still trying to figure out how to monetize those ideas besides with datacrons.
We also have to remember that chromium? players are still getting vaulted up into the top 100 of Kyber one because of some bug they created and they haven't fixed that yet. (It's only been a year, so I'm sure by 2030 they'll figure it out.) Bugs don't seem to be high priority unless they make PVE easier. Datacrons "once in a while" get a tweak if they do something unintended, but they still have quite a few bugs that are years old I'd rather they deal with first. Those are significant impacts to GAC and TW they should be fixing first.
Datacrons will make these maps way better or way worse depending on what type of garbage they make us rent for four months at a time.
