I never did much roleplay back when I played City of Villains in 2010, but I'm starting to get the hang of it after running a lot of Dungeons and Dragons sessions. As a matter of fact, I'd like to learn more about roleplaying in a MMORPG. I'm not sure if this is the right thread to ask, but would it be possible to give me some advice with roleplaying online?
