We had 5 advanced refine runes in group shop, when Oasis planned to give us lv11+ refine runes. When that plan was delayed, we got 1 advanced rune. Thus, even higher leveled refine runes are delayed even further. Whoever planned this must be a genius... Having 5 advenced refine runes might get people closer to lv 10 refinements and thefore willing to accept lv11+ refine runes, but whoever wants to think?
