This is a hard no for me, as too often, it entrenches the way the DM thinks a class should be played, regardless of whether the player chooses to play the class to be played that way.
this is something that needs to be walked through.
classes can have suggestions, things they do best (what I would call a role) but playing against type or even just a slight tweek of type should be fine and if it isn't the DM needs to be upfront about it... I love all of your examples but as a DM I want to bring up my own
If I pattern my rogue on Vidocq, thief-turned-detective (and inspiration for Javert), I don’t want to be penalized for not being a greedy bastard.
My bard sings hymns and seeks converts, I don’t want to be penalized for not seducing barmaids, writing terrible poetry or strumming a lute.
My barbarian represses his rage in most situations, and it only spills out in battle when he gives into it. I don’t want to lose XP because I don’t play him as an “ales and whores” cliche, or I didn’t take the DM’s bait when an NPC tried to antagonize my character.
Mechanically, my paladin has the Oath of Conquest subclass. Narratively, he follows the goddess of death, and has weaponized enemies’ fear of their own mortality.
so I had a 3.5 set of campagins... I was playing in 1 helping run 1 and about to start a 3rd. In the one I was helping run the idea the DM wanted was power house power game concepts... and I mean we used dumb Op Board stuff (hence why he needed some help) the second I was a PC cleric, and had a level or 2 before this time had taken leadership and by accadent made an OP druid that was better then the whole rest of the party put togather... so that is the type of things we had been talking about when I pitched my more normlish world.
So 1 player asked if I could have a barbarian tribe or two in the world before session 0... no big deal easy. I actually made an elf and a human set of barbarians along with the intermixing being half elves.
so session 0 (we just called it character creation night) rolled around and there were 4 players. (3+1 that had made request) and we went around discussing our ideas. We were starting at 5th level but no more then 2 allowed for race level adjustment... the first player pitched wanting to try to warmage or the warlock from arcane power. then the player I assumed would be a barbarian went next and said he would be a human barbarian 1/cleric 4. I was like "cool like a tribal shaman?" and he said something like that and went off to build... the other 2 now thinking we had a cleric made a Knight/Warblade and a Swordsage/psiwarrior. The orginal player settled on warmage and we took our stuff and the only item to really discuss was teh god teh barbarian cleric would worship he asked who teh god of war was, and I said all of them are warlike but here is my list... he chose one that had war healing and knowledge as domains and we Bsed a while.
game 1 he does this weird self buff thing and runsd in and basicly out fights our two warriors BUT at this point it is all high 5's and how amazing his character is... until the end of the first fight when the warmage asked for some healing...
"I don't heal"
I thought I heard him wrong "You are a worshiper of my god of healing knowledge and war (remember all of them had war) and you don't heal... you don't even need to prep the healing spells you can just spontaneously"
he interrupted me "I wont heal. My spell slots are for me an not a team resource, go get a wand"
so when the party got some loot before splitting it they bought 2 wands of cure light. then split the remaining money... that player complained he shouldn't be 'shorted' money since he COULD heal himself (and he did).
so they gave him the wands and he said "I wont use them to heal you I am not a healer" and the game blew up both in and out of game into a fight...
As the DM I layed down my ruling that this went against the table rule of playing as a team/group. the fact that we thought we we geting a shaman, the fact that he didn't say anything until healing was needed even as we all considered healing to be okay in the group was a violation....
I don't mind you going against type but you have to tell us. 4e (and we still use the terms now) helped with party role... You want to play a celric striker cool but be upfront don't let us build a controler/defender/striker party around your leader then refuse to heal.
As I ttyped this I am reminded of the guy who tried to charge party members for healing in 2e...
