I raided throughout all of vanilla, tbc and wotlk
The last time I legit enjoyed raiding was probably around the time we first killed illidan. Farming illidan for around 6 months and then Sunwell...and then all of WOTLK hundreds of raid nights....all those nights I was raiding out of pure habit...I didnt enjoy it...I was bored of raiding the moment illidan fell in half way through 2007, year i still felt the need to keep raiding the rest of 2007, all of 2008, all of 2009 and a bit of 2010 ......and yet I maintained 100% raid attendance the entire time...not enjoying any of it...hating the progression raiding, hating the farming...hated sitting at my PC all those hours.
It was only when my guild finally decided it was time to disband our raid team after we got LK heroic...many were burned out, many of them the same guys I first went into MC with.
Then I found myself in a inactive guild with no raid team....and suddenly I had like 15-20+ extra hours free time on my hands.......now its been nearly 5 years since then and when I think back I cannot imagine how on earth I had the ability to sit there and raid all those hours....nonstop....for years on end...always locked down into a time slot that I had to be there for.....it blows my mind that I was even capable of doing that. The only explanation I can give to myself is that it must have just become a huge habit....a very bad habit.
