PVP Mode is always disconnecting

Im Monk lv50 and in ASIA, I always checked my sever and ping was ~50ms. But when I started every game is started freez when couting down to 2 or 1, or badly, when I started fighting, I saw my opponent had no moves and I know I had been disconnected and I lost that game. And the matter is, I tried many matchs, now, my rank is 9 and 1 star. It is very disappointed because almost those games I was holding advantage. )) GLU ADMIN, Please give us a time waiting for reconnecting. Thanks!
