Ahh you do know that you are just proving my point???? People play mainly fighter,rogue,wiz and cleric build. The rest of the classes are for memery lol,the old jaded player picking a druid for the joke because he is done the wiz build far too many times and it is bored. You can't argue about minmaxing when trying to pick a different party lol. All those four classes are masters at what you need them for to cover all you need in a party.
Wrong for 5e. Fighter/Cleric/Wizard/Rogue is a balanced party but nothing more. Its not even the strongest single class 4 man party (Paladin/Moon Druid/Lore Bard/Wizard) if you add multiclassing to the mix its not really comparable. For the rest it depends on the game version, but the rogue and the fighter are better replaced by halfcasters or multiclassed in almost all DnD versions. Rest based magic is potent.
Not talking only about 5e,but in generally. Well those classes are the best for what they do in the party lol,the party is balanced because they cover their weaknesses. In a party on party fight they will most likely beat the rest. Single class party is like a one guy party,a joke that experienced player do when they feel bored or want to challenge themself with a different play style. Lets be honest here,most people here had done that shit in different game,but the codex is the top of rpg fans,normies really don't do that shit lol.
As a pure class comparison those for are pretty much the best at what they do and the other classes are variances of them. Fighter could beat any other melee class,cleric is the best buff/heal character and other classes are just a mix of cleric and something,rogue is pretty much unique class and there is nothing that could cover all of his specialities,the wiz is maybe the only one that could have a equal in the sorcerer but it is more of choice between versatility of the wiz and the power of the sor.
