A 10.5s duration means that DRK cannot get a five Spell Blood Weapon at all. Queue into Levelling Roulette and get The Aery? Enjoy your 2.4k MP Blood Weapon, sorry your resource generator doesn't account for Spells. They're gonna need that leniency as long as their kit is split between Weaponskills and Spells. And I realize this is just for their AoE which is a big ol' "who gives a shit" since it's only relevant to dungeons and has zero impact on the endgame, but dungeons and levelling and what not are still an important part of the game and the Job should function at all levels. Like I said, at the end of the day you're still left with half the problem still there which will require more complaining that SE will continue to ignore but hey, at least it works properly for part of the kit now, right?
