Game is unplayable, fix your game

After 650 hours of gameplay, the game has become unplayable since last patch.
For days (for some people its been weeks) the game has become completely unplayable, plagued with constant error [G0x9-SPELPWP1P2NT] and very high ping in instanced content 50% of the time. It is not my ISP, every other game works perfectly.
That coupled with a 48h ban mistake with terrible support, game based on RNG gear upgrade for progression, people disconnecting willingly from raid after a wipe, many players being AFK in every PvP games, random 3 or 4 crashe of the game without any log.

Im done till you fix stuff, my time is much more valuable. Good luck with the game.
