Well, that doesn't really make sense to have 2-man mechanics in place in old raids. They lifted requirements to be in raid group, but does it help, if same gunship blocks 80% of ICC? Or gunship is skippable now?
KZ Chess also should be made skippable. Or is it already? I miss shaman pre-MoP totems as I could completely ignore all mechanics on chess event by cheating with healing totem, making my chess pieces completely invincible, though it was still quite a boring tedium.
I wouldn't go with mana-based class as well. Hunter/DK are good to go through this encounter if you have them as alts. Your mana pool is constantly decreasing down to 0 maximum MP (sic) on this fight.I think pets can kill it for you, like shaman Fire Elemental. As a rogue, you are out of luck I believe.
