For the most part I would agree. However from my experience with dual warrior pk, it really doesn't work. The moment you run into a party with a debuffer u gotta town or run until ur buffs come back. Very difficult to take down a target when ur fully duffed even if both warriors are baba'd up the ass. Then again my experience was in ardream where both warriors were rolling with sword aura instead of cleave/descent so maybe the dynamic would of been a bit different with descent. Then again cleave does fail a lot.
I believe it was mentioned earlier but sin+lightning mage is a very interesting duo at least in cz. I wished I frapsed it but I remember about a year and a half a go I witnessed first hand iSinins+BadFamily light mage (forgot name but dude had a chaotic +11 rev and bordered nazi) take on me (warrior)+ 4 Integrity warriors (Orochimaru/Im4Opti/xXMoHoHoHoXx/BrazilGirl) + 1 Integrity sin (Ceacker I think). The lightning mage would throw up a blind and then sinins would take out myself and Ceacker while tanking all the warriors and just before he red balls and is about to die the mage tps him and then basically it was rinse and repeat. Couldn't touch the mage either with the blinking. I know people like to says sinins was all gear but the guy actually had skill too.
