The way I see it, both Golgoroth and Oryx have cheese strategies. Not game breaking like the others, but cheese nonetheless. It's bypassing game mechanics (add control around Golgoroth and the vessel and light eater knights on Oryx). This is in the same category as choosing who teleported in the Vault; manipulating game mechanics. That being said, this raid is easy regardless and I don't see why people need to use this strategy. It seemed to make things more difficult for my raid group. Maybe we just got the strategy down after 6 hard mode completions, but still... sad how it's only going to become more of a joke.
