Well I am very disappointing too I really "REALLY"" wanted that claymore that Is why I even bothered to farm for hours. I really hate when online games give items to "selected few that where here first"
I play games to relax and checking store constantly gives me stress. This limited rare item quantity shop will be the downfall for this game it will push many people away like it did to me.
Is it even possible to farm that much? The game had gotten so laggy and the rewards so limited that I gave up on farming and made the mistake of waiting for the Kickstarter karma instead.
(The claymore was the last deciding factor for me and made me go ahead and pledge.)
