Curious about reward changes for the future

GoingBack

There are several areas of the game where rewards or items have been pretty stagnant. I was wondering if I have missed any timelines or roadmaps for increases in the following areas:
AQ
AW for lower tiers and win/loss crystals
Arena
Incursions
Black ISO store
Glory Store

I assume the next progression level will address the daily, 4-hour, etc crystals. Just tired of getting the low amounts of gold (also why do we get low tier ISO from Cav quests). Possible the next progression will also see a new MQ difficulty as well

Again there are several areas that seem just seem outdated and an increase could help to pump some life back in.
