All in all, people found it hard because they wanted to burn everything instead of dealing with easy mechanics.
No, it was not just that.
All four bosses used the "adds spawn at X% HP" mechanic, but because most players were in i70 to i90 gear and PS and it was tuned for i60 problems started occurring in the bosses timings.

It was fairly easy to unintentionally burn the 1st boss to the second add wave trigger when the first set of dogs were spawning. This would not have been so bad if the debuff the dogs and the boss' AoEs applied wasn't a near instant kill explosion when you got to many stacks.

Zu (2nd Boss) gained enrage stacks for each egg broken and lost them over time. Because the eggs started hatching based on the boss' hp% but the enrage stacks fell off based on time a group, doing the mechanics properly (kill only the hatching eggs) would cause an enrage if your dps was to good.

Siren herself was basically a semi-HM Primal fight. One of her adds would chase and gaol the tank/healer if it caught them, every so often she would do a wide charge through the center or a room wide aoe that require being in the center to dodge (and it was random if she would charge or aoe each time), did a the healing down debuff was every 30 seconds on a fairly short cast and she was the first appearance of a "heal to full to remove" debuff in game. If you did to much damage to fast you could end up having the adds spawn when the tank/healer needed to do something.

All of that combined made for a dungeon that was not worth the rewards it gave.
