I also get the burnout feeling from time to time and what I do is I just stop playing for a few days. Or I go do some PVE since I mostly PVP. This week was so bored of PVP-ing that I went through the effort to make a 10 main raid to do the weekly quest. It worked out nicely. I think I'm going to start raiding but I will have to make a set of PVE gear because I haven't known anything but PVP until now.

In my opinion, us boxers feel powerful for a while when we take down everything so easily with 5+ chars, but what happens over time is you start isolating yourself too much since you no longer need to rely on other people to achieve goals. But eventually that makes us feel too lonely and burned out because after all humans are social beings no matter how antisocial a person is.

So I'm thinking to either start a guild or join a PVE guild and start rading with one toon, but only like once a week or something. I want to get back into the social aspect of the game, which you can't get in PVP-only guilds.

Or I'm going to park a paladin and bring another player with me in daily heroics or something. Anything that gets me to connect with other people.
