I find the whole ordeal to be ridiculous. I'm a strong believer in the fact they should have made an offline mode of sorts but it's already too late for that so I'm not even gonna waste my breath on what they could have done to do that. I'm just glad that by the time I'll be able to buy it, the majority of the problems will be done.
Really, I think if every person who was going to buy the game joined the stress test but a lot of people probably just didn't do it either because they didn't know about it or didn't have time to join. They should have thought to themselves "okay well this works...so let's quadruple what we have now."
