The class design have too many important combat spells nowdays, because back in Vanilla, Wrath and Cataclysm, it did guide them fine what to read and use abilities with 24 abilities being put two of the main action bars, with buffs and non-important/combat spells (for example: Blessing of Might and Seal of Truth) were easily put to the action bar 4 and action bar 5
the Dragonflight has more than 29 important combat spells, but 5 of them are put to action bar 3,4 and 5, even CCs from hunters and any healer because they cannot handle everything in PvP
Also we want pruning abilities, just like Legion, they had less than 23 important and combat abilities that were put to the main action bars (1 and 2)
For raiders and PvPers, they were so healthy to play these class design during 2016 and 2017
and for those who joined WoW during Legion, they had so much fun, they didn´t have the problem with Class Design, even the raids, because Legion was the EASIEST raiding expansion since Cataclysm.
Only 1 Legion raid was hard, for example Tomb of Sargeras because of so many troubles in Mythic but the rest were easy
