How does it even work? Because I've seen boss skirmishes go down in seconds with 10+ people there and then the same boss skirmish fail with 3 people doing everything they can and it's like they're trying to break down a steel wall with donuts. Hell I watched a skirmish go from 0% to 88% and when I got there, there was no one there. The NPC's had wrecked the boss before anyone could get there.

Someone explain how this works...
