Try something new, I tend to switch my roleplaying style every phase the server goes through. In 1.0 I was Ascended, 2.0 I was Teutonic, 3.0 I was Orenian, perhaps in 4.0 I will go Elven or Dwarf? A good mix of roleplay is what makes you get the full story, and not just some small part.
Then bring back your old character! Go out with them, hit a tavern, ask about current events. Find a job. Meet new people. All that good stuff. Fifteen minutes of interaction won't get you any roleplay; you need to go out and make it.
