Just keep on throwing out everything you got. It's almost impossible to get a ton of frontload threat on her. When you start casting AS she can walk in and silence it out of you. Also, you can't block when you are casting, so you can get crushed which isn't really fun for your healers right at the start of the battle when they are getting into postition.
I posted this somewhere else but this is what I did when I mt'd Maiden.
Put up SotC, put up HS. Ran in, and pulled her to the middle while spamming my judgement button until it went off. Then started spamming SoR then HS. Once HS was back up started spamming Consecration until it went off, then judgement/SoR, then HS, then consecration, etc... until she died. It's kinda hard to get the timing down with her silences, but she pretty much silences every 3 seconds for 1 second. Just pray that her silence isn't up when you need your HS to be up and that if she does hit you during that time it isn't a crushing blow. If your healer's are on the ball it shouldn't be a big issue though.
