No.
They take 15 - 20 minutes each and maybe I sometimes have real life commitments to take care off.
Kicking afk people though (those that join a strike then don't move an inch after spawning) needs to be implemented so they can be replaced with somebody useful.
You sound like the quitter who is picking and choosing. Most strikes take 10 minutes at most. If you really have to quit to go do something than you won't be effected by a 15-20 minute cool down. Wanna know why?...because you'd be busy doing this real life stuff you speak of. But let's be honest. There was no real life commitment.
