Here's what i am doing, trying to go for the angel soldier look, purity dye makes it look a little shiny and its got a very white knight look to it. I tried to get armor that didn't look to garish, for some reason i can't transmog the shield into one that i like, so im stuck with "ascended shield". I think a very popular (and boring) way to transmog your crusader is to go full ascended look and then dye it all black. I've seen quite a few people go this route and i wanted to stand out just a little bit.
i dig the wrathful golden knight look! Nice skycutter (that's what it's called...right?) too! I wish i had that weapon! or a weapon good enough to use AND transmog into it!, i personally dislike the hallowed helm, and in my opinion the gold is just too showy. But if you were going for the whole golden knight thing, i think you got it down!
That's a nice look Kinohike! Definetely stands out from the pack. Kind of makes me remind of the Faceless in World of Warcraft. "A Faceless Knight" or something along the lines. Really nice, though I wonder if Sacred Shield / Ivory Tower would work better. May not on a male crusader, though.
Tried to go for a black knight kind of a style. The ascended set is indeed very mainstream (although it does look cool), and I think I succeeded quite well with my set. Not sure about the boots though, there aren't really any boots that fit my set all that great.
