Sometimes when I play the game it runs silky smooth. But most times it just decides to run very laggy on me. Can you guys get this fixed?

All my other games and applications run fine which leads me to believe once the servers are upgraded this won't happen as much.

I have an:

i7 3630 2.4GHZ processor
2GB DDR3 Nvidia GTX 650M
8GB DDR3 RAM
Windows 8 64 bit
