Oh buddy you are going to make this one fun.
Anyone with half a brain can come to the conclusion that they are planning on using this for launch. They haven’t suggested anything otherwise except for sharding so why would you think they would change their minds on this? News flash, they won’t.
Only a child would think like this. YOU THINK THEY ARE RIGHT SO THAT MEANS YOU WANT IT. No… that’s not how the world works. You can dislike something and disagree with something, but understand the need for it at the same time and accept it. Do I like taxes. God no. Do you think I want to pay $4000 a year just for property tax? Who would? But I understand and will defend the thought behind the tax because even if it doesn’t feel good to pay, it benefits me in ways that are less obvious. Normally once you start paying for stuff like this on your own you will understand.
Again, I do not want this at all. I just can come to the conclusion that it will probably be beneficial in the long run even though it is something I do not want. And asking people to wait isn’t childish, it is common sense. If classic came out today and said, “Hey guys just letting you know for the first 2 weeks we are going to have the post-cata azeroth to level in besides the old”, I would think “Well that’s stupid, I am not going to play that… I’ll just wait till it’s gone”. Because that’s what mature people do.
Do you even know what they did with RP servers or are you just spewing off some random BS you hear people parrot on here all the time? Did you know that blizzard actually…DIDN’T lie about RP servers!!! GASP
Over the last couple of years, we’ve begun using some new technology we’ve occasionally referred to as “sharding” in non-instanced zones, which separates players in high-traffic areas out into separate “shards” of a particular zone. The benefit to our server performance has been massive - it was a huge part of why Legion’s launch went so smoothly - and so, as a whole, we’ve been very happy with the system.
The one exception has been on RP realms, where player-run events are much more common. On RP realms, we believe that the overall loss to game performance is worth it in order to support those events. If players on RP realms choose to organize an event and congregate somewhere, and have a laggy experience as a result, that’s their choice, and we’d like to allow them as much freedom to do so as possible.
So, we’ve recently applied a hotfix that should disable realm sharding in the vast majority of the outdoor world on RP realms. That includes Kalimdor, the Eastern Kingdoms, Northrend, Pandaria, Outland, Draenor, and all related sub-zones. This has actually been our intention for some time now, but as part of investigating some reports involving a player-run event in Northrend, we discovered some secondary issues that were causing it not to function properly.
There are still limits, of course; we don’t want playing on an RP realm to mean you can’t properly experience core game content due to low FPS or heavy input lag. As such, all Legion zones (including all of the Broken Isles, the Broken Isles version of Dalaran, and soon, Argus) will still have sharding active, as they do on non-RP realms. Similarly, when the game itself points players toward a specific area of the non-Legion world (such as for a holiday event or new patch content), we may temporarily re-enable sharding in that area until things settle down.
In general, however, our goal is to follow the general rule of thumb that RP realms do not shard, except in current-expansion zones, or when temporarily necessary to support gameplay. This should now be the case on all RP and RP-PvP realms worldwide. This is in addition to our existing rule that RP realms do not automatically fill areas using our Cross-Realm Zones system (although you can still enter an RP realm using CRZ if you’re grouped with a player on an RP realm).
Thanks for all your patience while we implemented the hotfix on this, and awesome job on the Tournament of Ages, guys! 
OMG Blizzards first response about sharding on RP servers ever said that they will in fact…shard during events and expansion zones. So we shouldn’t trust them because…they…told the truth? Very smart.
I’m sure there is a better solution somewhere out there. But by no means will it ever come out of your mouth.
