That was the other argument - it would hurt the activity of this forum.
the Knights of Ren forum was mention because the last couple times the lightsaber subforum has been brought up, that's been the basis for it. They did it for Knights of Ren, so they should do if sabers. They've basically devoted a subforum to Kylo Ren's costume. Which is odd, frankly. I know the original though was likely that the Knights of Ren would be fleshed out and there'd be 4, 5, or more of them to detail out. Well, apparently not. I'd be willing to be there's a lot more posts on Darth Vader's costume, but it didn't get a subforum either. Go figure.
I get the point at not splintering the main forum and killing it with sub's.
If the search were better maybe? If you were mandated to select a category (lightsaber, vader, Luke, fisto,, etc) so there were better ways to search as opposed to just grabbing words in a theread. I don't know. When searching i tend to use google so i can detail it a bit better and even then it's still hard to find stuff.
