I've been thinking about the various bosses in DDO, and have come to the conclusion that sorjek iincani is the best DDO boss, in either incarnation, in terms of interesting dungeon, interesting on your toes fighting, and the clear story he has the players participating in.
One reason he is the best imho is he, unlike other ddo bosses uses terrain to his advantage. From filling the area with defensive mists to blowing foes off the top of his mountain, to even drawing a party across a room only to have mephits spawn on the other side difficult to spot due to the mists.
No you might say that other bosses do simular things, but most, to me feel far more gimicky. Examples would involve monologue during which the boss is invincible, flying up, jumping up or teleporting up to a perfectly visible spot, but somehow being invulnerable while there. Super powerful bosses that are easily controlled or surrounded and defeated, due to total predictability, IE any pitfiend or lord of blades. The closest boss to sorjec is imho malucia due to her use of her abilities to her best advantage, although ever her fight in under the big top would have been much cooler if, instead of mass charming at scripted intervals, there were continuous small waves of friendlies that she keeps mass charming. The scripted boss events are the final reason sorjek is just that much better than any of the other bosses, as his abilities don't seem to have scripted parts at all.
Imagine if DQ could teleport like hezerou, and rage when ever she wanted. Imagine if velah could jump back into the air and place and inferno right on top of us. Imagine if aeritrikos's meteor swarm strafes were actually directed to ground that wasn't empty. Imagine if lord if blades was relentlessly using his abilities. Imagine if toven would randomly drop his shield, heal his pets a bit and then raise them back up and chug pots. Imagine if the stormreaver summoned all his massive armies instead of random elementals, and actually didnt give the players the ability to defeat him. Imagine if sully's agroo couldn't be held because he was teleporting around to engage anyone supporting those fighting horoth... Imagine if horoth disjunctioned before banishing. Imagine if the black abbot acted like the ascendant god of the undead rather than a xorian outcast and defended himself with more than minigames.
Please devs give us more bosses like sorjek incani... Or however you spell it.
