It must be so easy to do it when it is your job. The office will be full of professionals that must test the game in the most excruciating way possible and of course they are going to be serious about it and do it properly.
Not to take anything from them but it's way different from the reality of the actual players. If you are not in the top 50 guilds in the world, at least some members will not be online, at least some will have the girlfriend yelling at them etc.
For anything below those very first ranks of the ladders, it's definitely not just professionals in an office knowing the game inside out.
