Right now, if you lack the appropriate stats you just... literally lose RP. There's no recompense, there's no upside. It's just purely an impairment of the most simple elements of a role playing game- seeing people do things and hearing them say things. We can't spy and narc data, we can't pick up on other people's RP hooks, we can't learn about the living, breathing world when we just flat-out cannot see or hear what's going on.
I've noticed that when there's a decent volume of things going on, you don't get the messages indicating that things are happening. This leads to your character sitting in a bar or other RP hotspot and thinking the game's just dead, when the reality is that it's banging. You might catch someone saying something every fourth or fifth time, which makes rational characters seem like they're insanely muttering to themselves.
Suggestion: Keep the messages that tell you how crowded and busy bars and other such locations are. That's great for informing people about game state and combatting small worlding with newer folk. However, append messages afterwards, don't binary block them. "The room is alive with chatter and noise, and you can barely make out: XXYY saying ZZZZZ." As for simply straight up failing stat checks and not hearing anything, I don't think this should be anywhere near as common as it it CAN be. Especially considering that not every archetype should have to invest into a stat simply to RP with more than one person at the time.
Addressing only works well in small group situations. Even if you're in a group of 3-5 and everyone is using TO X, you'll get dropped messages. And I'd think that the solution isn't to take RP to private locations off-grid that are quieter, simply because that leads to a whole other basket of eggs.
In summary, I'd really like to see much less dropped emotes, poses, say and to messages, but keeping the messaging that was implementing to guide theme is A-OK, and a good thing, IMHO.
