Now that's a mythic fight! The first thing you learn about this encounter is that the dps requirement is quite brutal. However, in order to defeat Krosus you need more than just boss damage. Soaking and killing the adds is a very big part of the fight. Having too many adds up will most likely result in a wipe. Having people die to easy avoidable stuff as the beam, has the same effect.
Great job everyone!
