I agree with that since of course it may happen that I can forget or just unnotice that they have ended, but in fact 90% of time they both are up so it's not THAT MUCH of a difference.
And with that I can't agree, because that was my opinion about that issue and it doesn't matter if that was Rhaegar or you or anyone else. I would say the same no matter what.
What you say look cool on a paper, but assuming that Duelist is surviving more than 1 minute in aoe is wrong. Average livespan of a Duelist without a healer is less than 30 seconds when going aoe. Before you go in you turn on all skills and you pray to survive as long as possible.
