Royal Captain is simple, this is what my guild did:
Find a good corner, have MT, 2MT, 3ish man rot setup there. Set raid MA to a 3rd warrior, have him target the High Priest and the rest of the raid setup close to the High Priest.
Start the event, have a monk pull Royal Captain to the MT spot and have the MT OT him. Have 1 SK aggro Hanlo and kite him (he is slow, run 5 is more than enough, no bard speed needed).
We had paladins aggro'ing / stunning the wizards, and when someone in the raid got the "glint of steel" emote /audio trigger from the archers, they would run away from the raid (to basically where the trigger mob for event is at). We had the MT and the MA call when they got that emote to warn the rot / rest of the raid to back away. We also just healed thru the wizzy nukes, most would hit the paladins.
Once it begins, Have the MA warrior and the rest of the raid kill the High Priest fast. next move to the Head Archer and kill him, then kill the rest of the archers (no more "glint of steel" emote), then kill the Arch Wiz, then kill the other wizards. Then bring in the kite mob, kill him, and then kill Royal Captain.
The High Priest will rez his comrades, so killing him 1st is basically the key, and you can use enchanter pets if you do that on King for this part as well.
