Meh, was telling myself i wont reply but i am bored so
You are wrong, this is World of Warcraft, its always the same game and has been for 13 years.
It wont be changed in the next expansion, it wont be anything different.
Its not a new game, its not a 100% cash grabbing company like EA, its the same shit it has been.
Quests-->Collect starter gear to kill big named pixels-->Collect more gear for bigger named pixels-->Bigger named pixels--->Next expansion.
The quality wont change, nothing ever changes gameplay wise.
There isnt anything safer to pre-order than World of Warcraft really, assuming you have a brain about what the game is about and you arent crying on the forums "I DONT HAVE ANYTHING TO DO" while your main activity is Pokemon in WoW.
