Then, after 1 hour 30 minutes, we decide that's enough! We gathered everyone, counted to 3, and entered Drek's:
We kept dying but people were rezzing and going back in. He'd eventually run OOM on his healers!
It was working! They were going down slowly, but going! Our reinforcements were down to 82! Could we do it?
Yes! We killed them all! Now focus on Drek!
VICTORY!
