Never heard anyone knock a game for being creative enough that death wasn't endgame, and actually could contribute to the story even.
Furthermore, if a particular playing styles does make the game unnecessarily difficult, then that probably IS poor design. There should be conditions in place to ensure that character builds remain viable. Otherwise, they should have changed the character creation system. If creating a character with one set of major skills makes the game significantly more difficult than another build, then it's a design flaw. For instance, designers should not assume that players will adhere to the convention that most RPGs are heavy in combat. If a game is combat heavy, and character creation lets you pick your own skills, at the very least the character creation should at least warn the character not picking any combat skills will result in a much more difficult experience. Same goes for games like Arcanum, where failure to specialize (i.e. becoming a jack of all trades) makes the game significantly more difficult. If you want free character creation, you better design the game appropriately to support it.
Besides, to me it doesn't even look like that's what Gromnir is complaining about. I certainly don't see how his playstyle was in any way playing it like one would play Diablo.
