Guild Wars 2

After reading on Dulfy and then checking the new website to confirm, it seems like we will be getting 3 Legendary weapons in addition to the two back pieces, and not solely two back pieces and one weapon like many were commenting.

New Website

The launch of Guild Wars 2: Heart of Thorns will introduce the beginning of a new line of legendary weapons. Start building any of the three initial legendary weapons and collect three additional new skins – including their precursors!

So those who were disappointed and thinking that you were only getting the single weapon and two back pieces should now be happier.

Unless of course I have read this entirely wrong.

Anything in writing is a 50/50 shot with anet. You will not know what will be in the game until it is released. I will honestly be surprised if the arena makes it into the guild halls.
