I suspect the atma drop has been raised already, and it will be raised more in the future, as animus and novus are quicker with the higher myth drop too, and nexus light advance will be made easier in the future (but not until some further upgrade has been created and some time passed.)

As obtaining the relic can be done now in a couple of days and it used to take weeks, upgrading to Zenith now is super easy instead of taking weeks, it's logical the subsequent upgrades will be made easier as time passes. Getting ilvl90 gear took many weeks and now it's trivially easy to get.

New people that join the game have to be able to catch up in a reasonable time. The newest gear will remain a time sink and difficult to obtain but the previous ones will be made easier so that catching up is possible. Without that, new players would have a nearly impossible to fill gap with the first arrived.
