My problem is that the listed "hard" DCs for 4E are generally pretty easy to make. Example: a Hard DC for level 8 is supposed to be DC:24.
Well, I was referring to 3.x.
Whatever the case, the situation has to be role played out. Perhaps some like to just roll their bluff,
without even saying a word, or by saying: "I try to convince him to...."
This is not how I play this. I let the player explain himself in front of the NPCs.
Of course, I take into account the PC's skill so as to adjust the reactions.
Having said that, the players have to always take into account their "character's character"
Is the PC a silver tongued social freak?
Even if so, the player has to play him that way. His skill are there to make things easier for him.
No matter how good a player roleplays out a specific encounter, if his PC has a bluff of 30, there is no way
he can roleplay it as good as his PC would in realife. In that case, the bluff skill can come in and save the day,
even if the lie that was roleplayed out was not as good. Thats not to say that the skill will always save him no matter what,
but it should somehow affect the outcome of things.
On the other hand, a savage barbarian with 0 bluff, is expected to roleplay his PC correctly.
Even if the player wants to convince the guard, and has a good idea to do so, he shouldn't try it.
The character comes first. His barbarian wouldn't normally do such a thing, even if the player wants to.
That way, skills becomes important in the game.
If I come up with a super powerful build (yet with 0 bluff and a low charisma), and my DM
lets me roleplay out every social encounter just by taking into account my "convincing" skills as a player,
what's the point of another player picking a less powerful build with 10 ranks in bluff?
If the 10ranks-bluff PC has equal chances of making it through the social encounters, why did he even bother
spending ranks in it?
To conclude: Roleplaying comes first. A player should react to the situations as his character would.
Is his a social freak? Fine. FIRST let him roleplay it out, and then adjust reactions according to his performance AND according to his character's skills
Is the character a brute? He is expected to play him that way. Even if it comes down to him to make the social interactions necessary, no matter his performance, his character's skill should keep the effect to a minimum, if not to a complete fail.
Do the players want their PCs to be good at it?
Make them spend skill points in those skills.
Those skills are not fluff....
