I would like to try to use social skills when i can as I figure it creates a potential added element of excitement. The pass/fail gives different outcomes for your actions especially for intimidate and bluff. Outcomes one would never otherwie expect in some cases.
I find what happens now is that if my pc just lies, without the roll, the other player will likely beleive what I am telling them. If they do not I can just keep stretching the truth until they do. If they still doubt me they usually just let it go. No sense motive no ability (int/wis) check, is rarely ever used.
With the bluffing skill there is that chance you may get caught or better yet a chance another player will catch you. This can stimulate RP.
Sometimes the other players are like, finally a chance to use my sense motive skill.
But there must have been a ruling at one time where it was declared that players do not have to pay attension to such social roles. This seems to be well known amoung players across the server now and so I find most folk just ignore my rolls, like they never happened. I have rolled bluff and diplomacy checks and literally had folk say they do not have to pay attension to these rolls.
I remember folk abusing intimidate in the past. That strength fighter losing an argument - rolls a skill and bullies his way to an instant victory with one simple skill check. Like you all have said, Its just really hard to regulate/moderate how to use these skills, in terms of modifyers etc.
- I have also seen intimidate used with lots of subtlety, like a more physical version of diplomacy, as well.
I still like to stick to making checks for my own satisfaction though and will still make rolls an ability check, even if its ignored by others. It helps flush out the individuality of the character itself. I have something like 5 alts atm and I want them to all have different personalities, ways of thinking. Skill check remind me what each of their int, wis, chr are, which helps me define their special delicate snowflake personalities.
Sometimes I will do a int check to see if my toon will figure something I myself has figured out already. Maybe a wis or int check to see if I can clue into something, to keep it real.
Maybe I should start doing chr checks as well to determine how shy, friendly, obnoxious I should be in various relations as a reminder that some of my PC's have terrible CHR and others have high CHR...maybe.
Playing evil, I like to use Bluff to provoke conflict RP -It might be metagaming a bit, but it is an easy way to provoke otherwise apathetic players into becoming interested in what my player is up to...((what is he/she trying to hide?)) .
I wish we could find a way to enforce skill checks a bit more but in game, but using them, even for just personal use can still be fun.
