Here’s what I’d like to see in terms of gameplay:
PvE that switches from 2*/3*/4*/5* essentials to 3*/4*/4*/5* Essentials.
Bring the 4s around in the rotation faster and adjust the rewards to give two covers of each 4 in progression and placement.
PvP - just open up MMR across slices and for all CLs so people are not stuck seeing a scant few targets so often.
Bring your CL10 suggestions!
