I just said screw it and cancelled all my boxing accounts today, including 2 RAF accounts, at least until wotlk, and even then I'm not 100% sure I'll be back to 5 boxing, I'm just having too much fun with WAR atm. I will definitely keep my main wow account, but beyond that only time will tell.

Edit: Had a total of 7 WOW accounts, now just 1, at least for the next few months.
