Paragon already talked on the subject saying that they didnt use any kind of "clever mechanic" to defeat the given boss.
There are also some interesting posts about their raid setup and how it got changed from one encounter to the other.
There is also a summer post in their site with interesting analysis on the subject "symbiosis".
There is also the much mentioned but hardly discussed 25 ppl normal mode clear that paragon did on top of their 10 man run.
In other words Paragon brought the 25 people raid philosophy into 10 mans.
And instead of people saying "ty for showing to me how things must be done" they re trying to imply that paragon didn't follow the "rules".
As i stated in Blizzards forums...
"What rules? What is the goal? Who achieved it? In what mode? Where are the rest challengers of 10 man world first even as we speak now?
Vodka had 74 toons with 6/6 normal. Remember that. Not 25, not 35 even...74!"
You want small roster and convenience? Sure, but then don't complain about "overtuned" encounters and "easy mode" 25s.
