Yesterday i grinded to Legend rank in PVP Valor, the last game was kinda glitchy... the game said we were 12 ppl and when my friend am me joinend we were alone against 6 ppl. Then after 2 min other ppl joined, but we weren't even trying anymore, so the score was 116:16 ,then at that score the game ended like 2 or 3 min. earlier. After the game it showed me that i ranked up to legend and the game gave me [b]5 Masterwork-Cores[/b] like when i completed [b]every other armor Piece[/b]. But then i was unable to upgrade it, even though it gave me [b]5 Masterwork-Cores[/b].
