So what tips can we offer Knightless and others who are looking for ways to refresh their interest in the game? Rerolling is a big one -- I've always found that picking up a new class you've never played before can get you to look at a game in a different way. Running an instance that you haven't run in a while is always fun, too -- it only takes a little while to level up a character to Deadmines or Wailing Caverns levels, and both of those instances always renew my interest in playing through Warcraft. Running guild activities or contests are always fun, too -- especially since Knightless is a guild officer, she could organize some lower level runs or some "grind days," where guildies all get together in groups to level each other up.
Any other ideas for reviving a flagging interest in playing a character that you feel a need to play due to responsibilities or other connections in the game?
