This battle has the possibility to be the single most epic event in all of Disco history. You can count me in, provided it's at a reasonable hour and not on a Monday, Wednesday, or Friday.
In fact, I recommend putting it on a weekend.
Also, a recommendation on the re-engagement things, perhaps making it so that you have to fly back into combat with at least two other people? So you'd have at least trios of fighters instead of awkward strings of single people filtering in and out. Just a thought. Not really a good one, but still, it's out there. Otherwise I'd vote for 10-15 minutes. No death timer at all would just induce an endless battle.
