5E did a really good job of adding flavor to each class with the different career paths. Each class has some reasonable branch that gives more variety.
Why is multi-classing still a thing? I understand it's possbile to meta-game some unique gimmick or combination, but at that point are you really "roleplaying"?
From a spreadsheet analysis standpoint having a good multi-class is actually difficult. The sheer power lost from not getting the higher levels in a single class is significant.
I've been a DM for 20+ years, and all my PnP players eventually regret multiclassing at around level 14.
Overall, mutli-classing seems to be MIN/MAX for mid-game only. ( Yeah... It is fun to see how CRPGs handle it on a system level )
If 6th edition removed mulit-classing, and focused on refining action econemy and spell meta-data, would you like it more or less than 5E?
