Well, to be constructive we could all throw out some tips for each other. For example, on the second boss, many of the groups I've been in have wiped on the adds because people use their off gcd stuns too early on the succubus. She'll build up a stun immunity and then can't be stunned when she casts beguiling mists. I'm fairly certain silence is a better alternative than stun for this reason. I main a ninja so I just switched to viper and silenced her instead of stun. Not a huge revelation, but it might be helpful.
