Exactly,
You need to be able to trust that the other player knows how to keep ic and ooc separate.
You need to play with good players for this reason.
Many folks who follow the forums know that Rigwyn is a bad guy - and that's putting it mildly. But when they play, they ignore that ooc info and only let their characters act on what they know.
They may know as a player, that they are about to get robbed or screwed, but they do not let their characters react that way.
This is not easy to do and takes practice.
Likewise, if I see I'm surrounded by unfamiliar characters with "Adani Order" guild tags, I have to ignore that info and be vulnerable even though I know I'm in for a hell of a beating. xD
There is a lot to learn about good role playing.. That's why I say to get connected with many good role players as you can.
RP can be a hell of a lot of fun once you get the ground rules figured out!
Whisper Bless!
