LOL...show me where Blizzard states that they implemented server queues so people don't all bunch up on the same server. And if load balancing could solve all the problems...why have more than one PVP or PVE realm/world/etc? Because even with tons of servers if you have too many people in the same area it's still not feasible. And yes, Blizzard has banned people for crashing entire realms by getting too many people to congregate in the same area quite recently:

If you have too many people in the same area chatting, questing, emoting, etc. in the same area I don't care how many servers you have all the coordination between the servers and with the players is just too much to handle. Why do you think Blizzard was so quick to ban the dude from the link above? Yeah, they later reversed their decision but he crashed multiple realms when he did his giveaway because the servers simply couldn't handle it. And some people reference sharding as instancing within the same realm....which is how I used the term.
Who's the troll when you dismiss others without backing up your claims with any links?
