They'll be much easier next time as I will now what to expect. It's doing them the first time which can be painful if you fly in and get dismounted into a bunch of soldiers. If you are a rogue/druid/hunter, I guess it's not as bad as you can sneak in. I only died once and that was when I landed in a bunch of the PvP elites behind the barracks while trying to suss out the area. My invis was already on cooldown
I had no problem with the peasants. Though I did kill one of the night elf patrols first, so that may have helped. I just put living bomb on them and they died really quickly. It was quite fun for them to go screaming away on fire shouting "It's the Hoard"
