Something to take into consideration is how the DM runs the game. A DM that allows the 5MWD (or only 2-3 combats per day) is going to see a lot more full casters. A DM that runs closer to 6-8 combats per day is going to see a lot more Fighters, Rogues, and Warlocks, because they get most of their stuff back on only Short Rests, and can even go a while with only a couple of short rests. If Feats are not allowed, the Fighter gets quite a bit worse, as the ASI will quickly max out Str/Dex then work on Con, rather than getting cool abilities. If multi-classing is not allowed, I think a couple of classes become less exciting, because they work best with combos (I've not played in a game without multi-classing, so I wouldn't know for sure).
Yep if I get around to it I will state the criteria I use. 5MWD doesn't happen much in my games but neither does 8 combats. I would assume a moderate amount if min maxing for example a warlock player picks Eldritch blast and hex but not a full on Sorlock build.
