They seem to have somebody, somewhere making decisions that actually gets that they need to start scratching things off the wish list. From QOL features like alt friendliness and customization, to core system improvements like universalizing the Domination set activation and 86ing conduit energy and pulling the ripcord, they are off to a good start.
Now do more.
For not much more concentrated effort than they put into customization, they could unlock more race/class combinations, and should do so for 9.2 and not just as a 10.x feature. At least one more class available to every race and allied race, or preferably just throw open the whole thing. The lore excuses are gone; after 20-30 years of cultural comingling those barriers would have long since started falling and after the 4th War and the supposed more unified world they make even less sense. Can lore-wave it however they want just suck it up and do it.
If they like they can think of it purely through the lens of how much micro-transaction $$$$ they'd pull in on patch day
