What is the problem with that?
.......
I think you misunderstood or I didn't make my point well enough (english is not my first language). Let me clear things up:
1. Nothing bad with playing a death domain cleric the way described above. But stating that it's the only way is wrong imo. And that's what she stated.
2. Nothing wrong with asking the party to have a somewhat fitting alignment. But stating that the the party won't work if his alignment is not fitting (and she meant fitting as in correspond/conform) is wrong imo. It basically fit with her argument that paladins have to be LG anyways - so the party should be LG or at worst NG to LG. (which none of my friends ever agreed on before she mentioned it, and we dont take alignment very seriously anyway (also not her))
3. I never said, that following the books creates one-dimensional characters. I said SHE probably created one-dimensional characters (because she follows the books and doesnt add creative stuff). Granted, that's an assumption and not a very nice one. But I feel it might be true with this player.
I think you really want to make a point when there is none to be made. I wrote about a specific player I experienced. Nobody else. I am sorry if anyone felt it was directed towards him/her. I just wanted to share a personal experience with the person asking the original question above. Not attack anyone who uses the books as source for character creation. Thanks for he tips on character creation though.
On the flip side of your final argument
it feels like you make exactly the point you you want to critisice. I personally think not every player who uses "a crutch" wants to be remarkable. Maybe try making a character with a gimmick. Create a character without a strong archetype. Then use your imagination and creativity to make that characteristic work with your class according to the rule books.Playing against what the books say isn't a mark of imagination. It's trying to use a crutch to be remarkable.
