Players connot join the party while you are engaged in combat

[Kurokikaze]

You DC. You either win with what you have or you fail and try again.
The reward: Everyone who wins that fight actually deserved to, instead of 80% of people winning the fight with cheap weasel chickenwussing.

Convenient saying that now... I'm positive you'd be singing a different tune if you popped an NM using your hard earned items and lost your healer or tank. Sure you can try to survive till they get back but as it stands theres no point since they won't be able to rejoin. Congrats on time wasted; I guess thats what makes this game hard.
