More to note on this fight. She casts a jumping curse on one member. It does dmg over time to that player. Easily healed through. When it gets cured or times out, it jumps to another player in the raid. This curse stays on your raid until Melanie is dead.

When we wiped the first time trying her, the curse was still on us when we revived and as we attacked her again, we got a second jumping curse. Cannot confirm if this was a bug. Eventually, the two curses jumped onto the same person and the 2nd one dissolved.

Here's how we did this fight. Pull her two adds into a side room that you just cleared and burn them down - this prevents her from KBing the raid everywhere. Since she will not move from her spot on that mini stage, once the adds are down, stand to the left and right of her and burn her down as well (backs should be facing the book shelves). At no point should anyone's backs be facing the doorway, that's just asking for a fun punt and recover.
