At this point its is nigh impossible.
Wow has moved toward smaller and smaller scale content.
In larger raids class disparity was less telling but as they moved to 10 man raids it started showing itself with certain classes being ‘mandatory’ due to what they bring (often tied to expansion changes to the kit)
When Arena started it really highlighted class imbalance at least on the PvP side.
Now with Mythic + you can see that on the PVE side with all the ‘meta-comp’ chatter.
Add solo shuffle and the new augment specs as a cherry on that heap…
In summary, with all the diversity in class mechanics, the smaller scale the content, the more these differences will become min-max-meta issues.
