When looking at EQ raids most of them seems to be; Here is a boss, he has some abilities, figure out how to beat him. I think there is a lot of design room for different types of raids that don't just involve killing a boss or some trash. Some of my ideas are Expedition: The first part of the raid could involve a mission where the raid has to travers a difficult zone(s) to get to the castle or lair of the boss. This type of raid you would be tasked to get across the zone while dealing with obstacles along the way in a certain time limit. An example would be you have to trudge though a swampy marsh where random creatures ambush the raid. The marsh has a snare aura that slows progress and random emotes could go out that cause a few players in the raid to become sick with difficult to cure ailments (200-300 counters) and you only have 10-15 minutes to get across. Or another example is a rocky mountain pass that splits into multiple paths where each path can only have so many players in it so you much split your raid while dealing with trash and rockfall auras in a very tight corridor. The idea behind these types of raids would be to test the raids ability's to manage their resources, organization and pacing. You could even have different sets of loot depending on how fast the raid made it through Defend the Castle: This type of raid would be where the raid is tasked to defend a structure from multiple points of attack. There could be different types of enemies that would require different types of responses. The enemies could bring in siege equipment and you could decide to try and run out and destroy it taking a lot of damage in the process or sit behind your walls and try and range DPS it down. The enemies could also try and dig under or scale the wall and it would be up to your raid on how to respond to the threats. The point of these different types of raids is to get people to think differently and come up with new strategies they had not normally thought of before and to challenge raiders in a different way.
