Ok. These are my and Steel's observations, along with recommendations.
First, the Captain is red. Hits hard. Every time I died it was to the Captain. I could stand up to several blues with some effort but the captain would take a swipe at me and boom, dead. Recommend warriors only focus on him.
The mini’s. All 3 are white and all 3 are sergeants. High resistance to pally stuns and undead slows, but vulnerable to pally undead blasts. They are not immune to the stuns and slows, just a very high resistance. They do not do too much damage. Recommend having SK’s tank them. Also, when we have chanters have them tash the sargeants to see if we can get stuns and slows to hold -- if we can that would solve a lot of problems.
One mini, Sergeant Grady, has a nasty root. He gets agro on you if you have agro on any of the minis or on the Captain. His root seems to be zone wide. It is definitely a huge range, one of the SK’s in my group died a ways away due to the root and I could not rez him. Strongly suggest we burn Grady before we try anything else.
Blues are wimpy, their only key is they keep respawning. They are not pally slowable but all (except maybe the scouts) are stunable. Recommend that pallies tank these with stuns and undead blasts. Will figure out the correct stun spell lineup because a stunned blue cannot do any damage whatsoever. Which is nice.
