Floor 1 - npnp. It's only bad when someone doesn't get the add in beam properly. My heals they BURN.
Floor 2 - Basically Coil t4 in a nutshell. Ez mode
Floor 3 - By far my favorite one. Just lots of mechanics and I've always been a fan of negative/positive since Thaddius from Naxx. (Yes WoW reference deal with it lol)
Floor 4 - Endurance Fight - I like it just requires 100% attention. It's hard I honestly can't wait to see this fight Savage. ;o Judgement on Healers/I like this Mechanic lol
