Then your analogy still doesn't fit, though. For one, raiding is a team activity, cycling isn't.
Despite fail analogies or not, I thought I'd correct you on one thing.
Cycling is very much a team sport. People take turns on the front to allow others to slipstream. Team members attack and force others to reign in the attack at the expense of tiring themselves out to prevent a breakaway. Hell, people even drop off to the back to pick up food and drinks for the sprinters / climbers / whatever to save them energy so they can better fulfil their role for the day. Perhaps the best example is the roll out train for sprinters. If you understand whats happening its like chess at 70kph, its amazing. It's a team sport through and through.
From what I understand, flex raiding will take the lockout of the raid leader(the one who queues). So if the raid leader has killed the first boss then everyone will start on the second boss. I know you can repeat bosses, but my question is would you get a fresh lockout with a raid leader who has already cleared all four bosses?
So if I clear all four bosses in group then come back the next day to help out another group, where would we start? Do you think it would be advisable to bring an alt to queue up so its fresh then relog into my main who has cleared all four bosses to insure a 0/4 lockout?
