Just a new graphic and I'll be happy...
I actually use KJ quite a bit, it does pretty well, more or less interchangeable with RR depending on the mobs. It's not like SC, where it's very situational.
I believe it does, on a mob like JoL with minimal buffs Steel Cyclone @ 100 TP often outperforms a full return RR or KJ, which shouldn't happen. (Are you the same poster who just made the post on the BG Randomer Question Thread? I just responded there with the same answer lol)
I've seen better average results from SC on things like Dynamis Xarcabard mobs (NMs particularly) too. Not sure if it's simply the nature of a highly modded single hit WS, but it wouldn't surprise me if there was some sort of bonus too.
I pretty much swap out ACC for STR/VIT wherever I have gear for 'em, doesn't seem to hurt it, but I do have full GAxe merits and all that.
