-DA should fit, but if we get flat DA reduction then it’s redundant with existing soldier skills, and stackable -DA isn’t normally found on skills that don’t specify a duration at the start of the description (look at CoF and vulnerability. CoF states at the start that if has 5 or 6 seconds duration then specifies all the debuffs that will be applied. Warcry doesn’t have the same wording so I doubt you can put -DA there.
-OA doesn’t fit, imo cause with warcry, you want people to hit you. Reducing their OA is the opposite of what it wants to do.
Tbf, my transmuted IK sorc can clear cruci in 10 mins (on my laggy laptop) with an offensive devotion and skill build (meteors, fissure torrent then devastations). Expect those classes with more RR (pyro, purifier) to clear faster, hence fluff’s 9 min results on purifier. Pyro should be able to do it but you’ll need more carefl play because it’s the squishiest among the three. If a very good player plays it then it should be just a lil bit slower than purifier (kalastor> fire doom bolt) but for an average player it’ll probably be just as fast as sorc
