With the fact it's on a Mi'quote and I'm a Roe, I'll reserve judgement, but that does look underwhelming for Dark Knight. While the glow is impressive, the blade itself is very basic. The Guillotine of the Tyrant is way more impressive than this thing is.

But I'll reserve judgement until it's done. I can't think this is the final form, but then I look at everyone else's weapons and they look fantastic and DRK, WAR and NIN are....well...yeah.

I'm at the point where I may very well do the same as some people suggest and finally glamour my weapon. Haven't done it at all this expansion but this isn't really looking great.
