Since you intend to waste time with troll posts, this is entirely inaccurate.
WOW dropped severely thanks to Blizzard not caring about it's quality of content, etc and putting cash shops in front of everyones screens in game. Nothing to do with the parser. None of them were killed by parsers, only decrepit old age, whatever you got against parsers is purely your own issue to deal with, as I said it's mandatory in the raiding community.
Now back on topic.

Paladin can keep it's rotation, all it needs is potency tuning to make Atonement severely a lot higher in it's attack power, and tune down Holy Spirits so Atonement is the overall bigger number, Goring will hit before the raid buffs fall off. Holy Spirit numbers need cutting down to prevent GCD drifting off, skipping 1 GCD twice in a fight in SHBs actually pushed it's aDPS higher, or no skipping for full focus rDPS. All in all that's all Paladin needs, is gcd fixing. It was syncing raid buffs long before EW.
