Every top ranking ret in the world????? That is a pretty bold statement, and even if for some odd reason you personally know and talk to all of these people, namedropping really doesn't prove anything.
No, silly, there is logs for that and they prove everything.
WoL rankings also prove nothing. Our class is way to RNG dependent and the top rankings really don't tell the full story about how the cd usage is working at the beginning of the fight.. There are just too many other variants that can occur over the rest of the fight that impact a top parse.
Outdated excuse about RNG. /yawn
Tier ater tier you will see same people populating WoL Top20, it is not because RNG loves them, it's because they know how to play their class to 100%.
Let me ask you......have you tried the other cd usage method for a full week of raiding? Maybe this is what your referring to as your "personal experience." If not, then what are you comparing to??? If you haven't tried and compared both methods, then your basically just saying "my way is right because I say so," or because a few other top paladins told me so. The people involved with the conversation have all said that math is the only way to prove/disprove the topic. Saying that its wrong just because you feel that its wrong isn't really helping the discussion.
200 pulls of Rag is enough to try everything and yes, "stack all" method produces best result and it's the only way I can climb to 2nd spot sometimes (after legendary mage) and stay in Top5 before first sons phase.
And no, I'm saying it's better because I have logs to prove it. You don't.
