Instead of rolling out useless UI upgrades no one really asked for, maybe you should consider unducking the mess that 7.0 caused in the overall leveling and class experience.
Having to choose between 3 core skills that you had before and losing other ones entirely made some classes a lot less fun. Combing together some skills to reduce the overall number of them is one thing, but this...
By having to choose between dcds, stuns and dash, plus removing some stuns and other skills entirely, you kinda removed an individual player's agency in combat, making me (us?) feel a lot weaker or at least it feels more dumbed down.
Not to mention you stretched out the remaining abilities in an 1-80 interval, which made the leveling completely trash. I think no one would be mad, if you'd rearrange those skills and spread it out in a smaller interval 1-70/75 at least.
In the old system, the order in which you got your skills got made sense. For example, you received your first aoe abilities early on, so you did not have to bash every stupid klor slug you came across with your basic baseball bonk skill...
