Running low on DCs doesn't mean that you're a lousy role-player. It probably means that you RP in the time most inconvenient for the DMs or then just some DMs don't prefer your RP. Nor does having tons of DCs imply to that you're a better role-player than someone that doesn't have as many of them.
You mustn't RP because you want them, you must RP for your own joy. Of course it's always nice to get them. In my opinion it's just a treat to encourage RP and events, albeit you never should RP just for DCs.

or then just some DMs don't prefer your RP.

My personal cue is that give your character flaws. Makes the RP more colourful.

Make sure you wave that little green wand of yours

We give too many DCs. We don't give enough DCs. We only give our special friends DCs. We intentionally don't give you DCs. Etc. etc., we know, we know, heard it all before.

We all have our opinions of excellent roleplay. If the DM doesn't think that the player's roleplaying is excellent at the moment, why wouldn't he/she not give a DC? Sounds perfectly sensible to me.

It's rather the other way around, actually. We (I, at least) are so afraid to subconciously favor our friends that we compensate by not giving them DCs in many situations when they'd get one if we didn't know them.

The secret is, you get so far into the RP that you forget the OOC side of things, forget the DC's, and immerse yourself in another reality. And when you are so far into it that you start checking around the corners for Drow when you go to buy some milk... ...then you will start seeing results!

And forget to use the damned wand to recommend your rp *face palm*. Happens to me all the bloody time.

Actually, I've had DM's warn me that they will not reward a DC if the suspect that I am/was involved in a DM event -only- because I knew it was a DM event.
Yes, DM events are good opportunities. But they don't even guarentee it.

Don't believe them, not all DMs think that way! I want my players to acknowledge being in a DM event, I want them to join only if they want to be involved in the event and I want them to make an effort to impress me with great cooperation ICly and OOCly, and I want them to show great enthusiasm about the event.

I mean... why am I even running the event if my players don't show interest and help me carry the plot onwards? Passive and/or nonchalant players are no fun!

But I guess that's not exactly what the DMs meant, anyway. I think they meant they don't fancy players joining events just to get quest goodies. But this is such an important thing, players must not get the wrong impression about how to behave in events!

Wand orgy!!!

We had one last night, all the evil villains in one bed room....*shifty eyes*

Oh. I got beat to it.

I always give DCs to players participating in my mini events if I see them roleplaying, and making some sort of effort. There's only one catch. I wont give them out if they ask me for it.

Those who do not demand them shall be rewardeth!

Though, *smirking behind the helmet* is one of those unnecessary emotes... you want to tell others what they see, and they can't see you smirking behind your helmet, can they? They don't even have a clue there's something going on under your helmet.

I disagree. There are many ways to do it; you don't have to conform to your style of only describing information available to ther other characters. You can also use emotes to communicate between the players to tell a tale in the style that would be common in a novel (all knowing perspective?).

Not all information needs to be safeguarded from metagaming etc. And the people I RP with, at least, are smart enough to decypher what to react to and what not to.

That said, "smirking under the helmet" is not very fresh, indeed.

EDIT: Didn't mean for this to come out aggressive or hostile, in any way. Just to be sure.
