I sit in dueling circles alot and i know these people and they happen to be very skilled at dueling. So i'm confident that my competition knows what they're doing. Of course everything is subjective. I just find that nimble brew lets me go stright on the offensive unless they wanna pop a vanish right away and of course they'll be sitting stealth for 25+ secs waiting for stun dr to go away, I think this puts me in favor fo the fight cause now i can revert back to my 5.1 style of play, waiting for the right moment to trinket. I also like to keep 3 healing orbs out before the duel starts, Helps to just run over them to recover from their burst.
I agree that you dont HAVE to nimble the opener, I've just found that with my damage, i can frontload so much preasure onto them that they'll start blowing more CD's to survive that DR stun period. Or they just vanish and reset the right to 5.1 mentality. But there are ways to deal with rogues. I should rephrase what i said. I havent lost a duel where i didnt screw something up, Of couirse i'm prone to error at times and i trinket things i shoudlnt and lose, we learn from it. But I havent lost much to rogues since 5.2 hit. Nimble brew is an amazing equalizer in that fight
