Allow us to add a socket to set items. Or, just have set items not be able to spawn as two-socket. It’s already quite difficult to obtain the set items you want as a triple-stat, and having two sockets makes any triple-stat worthless.
A way to add points to aberrant pet’s attributes. Perhaps make it cost a certain amount of spirit essence per point (so we have something to do with the thousands of extra essence). This would enable players who grind to see rewards for their effort.
Make new types of fishing bait that allow us to skip common/uncommon/rare fish and or quicken the fishing meter. Five minutes to catch a cod is exhausting.
Rework the charm system to be like the essence mastery system. I.e. have a mastery level for each skill and feeding charms to said system adds buffs for skills. The charm system is outdated, and the market for charms is stagnated.
Take the third stash tab off of boon of plenty. A lot of players keep one of each set piece to class change and utilize different builds. With bracelets, you now need to have the third tab to keep one of each set item. The fourth tab is fine for boon, but the third is just greedy.
Allow us to disable back accessories for certain cosmetics the same way we can with helmets.
Just a few thoughts
