i have to agree on this ive seen so many people, where i know theyve been "using" and got kicked out of really good raiding guilds just because they had the mindest "when i use pqr i will be like one of the best".
like last week we had one guy kicked out of our 25man because he was using his personal dps cooldowns like a retard everytime on cooldown not even waiting 10-20 seconds for fixed events to happen in a bossfight where everyone else was using them in combination with bloodlust (iron qon after dam'ren has been "defeated" and all 3 of em with the boss are there)
its not always about "perfect" rotation but also about anticipating the next move or thing to happen and there the most flexible profile where i as a player can say "no you wont do this now you will do this now" simply wins because i can pull off so much more dps
