Ahhh, nice idea, only problem i see with that is when there is more than one red guild attacking, i sat there yesterday hidden, crying and snivveling while two red guilds fought for barracoon, first guild came in and killed me, cleaned up spawn, healed the little damage barracoon had and started to kill him (took them maybe 20-25 minutes) just as he was about to die another red guild attacks fight off first guild heal barracoon again and start to kill him (takes another 30 mins), then first guild comes back and attacks, fight off second guild and finally kill barracoon, I was hidden for best part of an hour, got two 110's. I think if the heal barra and kill it gives them a better chance as they are doing more damage? Ive seen reds almost kill him heal him then kill him.
So unless you can see whats happeneing you have no idea how long to wait.
