I typically use the thinking deeply or something similar. If I’m in an active conversation, I will say I’ve got to think about something in my head.
I don’t think this will ever go away.
This is a public server, you are going to encounter a little bit of everything ranging from hard core grinders, people who abuse the server by hacking, and dedicated RPers. Saying that not many people try anymore is offensive and not necessary. I have been with BigCity for around a year now, and made many great friends. I can assure you those who are here to stay, try very hard.
The quality of RP you experience can often be a direct result of the RP you create. If you want better RP yourself, practice and keep trying and you will eventually get a better RP experience.
