Guild Wars 2

I’d like to know if it is true that if you throw 4 Ascaloniam greatswords or 4 CoF greatswords you have a better chance to get Foefire’s and Volcanos ?

This sounds like pure pub-talk to me. So I have to guess no. The reason is that it is very hard to prove it is the case but more important for those really wanting those blades, there is a way of making them (recipe is on the wiki page).
