If you land three attacks in between WS, it will give you a 3%~5% direct damage boost, depending on your buffs. It's not much, but still useful (especially if you land more single hits). Imagine that kind of boost on equipment, and everyone would want it for every job.
And now imagine a nerf being announced to Scarlet Delirium. DRKs would throw a fit despite their universal acknowledgement that the ability sucks Chocobo balls. Dfoley's comment just was completely unjustified, no one in here freaked out because of this and no one demanded anything. He's making stuff up.
Me too, a little disconcerting that we still didn't hear about that yet. Although we didn't hear much about any job so far, other than PUP. I would really love if we could also discard weapon type with it and make it magical, like Formless Strikes. I doubt this would happen, but it's nice to dream.
