Two nights ago my Heroes By Trade group faced a very difficult fight. We were in a strange city filled with all kinds of demons / demigods / eldritch powers from an ancient time who had been sealed away by the gods. We decided to enter a building and found a statue there. Being extremely random we decided to break the head off of the statue and doing so caused rather a large number of monsters to charge out at us. The GM assumed we would run and by the numbers I am pretty sure we should have. There were too many enemies for us to defeat and if they had played intelligently we would have died.
Well, all the other characters would have died. My character, being nearly invincible, might have been able to get away or even win in the long run. This is a separate issue that I need to address.
However, the monsters were not at all intelligent in their tactics and insisted on standing there beating on the target in full plate armour carrying a shield even though it was obvious that their efforts were in vain. It is true that the tank was also the healer and normally Kill The Healer is an excellent strategy but in this case the best strategy was Kill The Squishy Ones and then deal with the healer once everyone else is dead. Had the enemies displayed even modest tactics and swarmed the people who were the threats we would have been quite easily crushed.
I don't know how I feel about this. It is certainly possible that the enemies were in fact mostly mindless thugs since they were insectoid monstrosities shaped like people in plate armour - who knows what they were thinking, if at all. They simply attacked the nearest thing and that might be all they were capable of. The other possibility is that the GM didn't want to just kill us all and decided to play the monsters stupid. He was pretty obviously expecting us to run but he didn't count on my playing my character Po right to the hilt - she is pretty much certain of her own invincibility and until that proves false she basically won't run from anything. If the other characters had been willing to run I perhaps would have followed but they all seemed to be waiting for someone else to do something and nobody stepped up to be that first person to flee.
I am not the sort of person that worries about the party all dying when I am a character. I have more characters buried in my brain and I can be ready to start something new and fun next week, no problem! I tend to be very wary of causing them as the GM though. I guess for me I wouldn't mind at all if our refusal to run got us all killed because it would set the stage for a much more tense and terror filled campaign next time. There is nothing like knowing that the GM will massacre you if you insist on being foolish and brave to keep you on your toes!
