The twelve hour concept is interesting and was nice to have explored. But, endurance is going a big issue.
I got up to take a break after almost eight hours of flying and fighting on TFT and fell hard asleep on the couch. I didn't wake until the next morning.
I would love to GL in this event, but it would be better for a player that feels they can make the entire twelve hours to lead and ensure plans are executed properly.
I will have eclipsed the half century mark while this event is going on or there bouts, depending on the scheduled day of the event, so sit, stare, and focus performance doesn't increase with age as Bruv eluded to.
I'll likely only fly three or four hours worth of this.
I think that is reasonable amount of time.
btw, I would miss the immersion of the AARs, the threads with battles pics, the many planes reports and planning for the next weekend. A couple of hours over a few weekends has been good for the last 16 years or so. Why change now?
