DON"T
That being said bottleneck is going to be rough in the starting zone the the next zones like westfall, silver Pine forest, and Darkshore. The first 2 months after launch blizzard should shard these zones to let the game be playable, but sharding needs to be done right.
First off a zone should not shard till it is so packed that players are lining up for respawns. If a zone shards it should still fill full. A zone before sharding should not just fill lived in, but fill packed. Let the full zone encourage players to group for quests.
If zones in the level range of westfall stay packed to the point of sharding longer then 4 months then blizzard should open up more servers. It is clear that WoW classic is bigger then expected.
Zones in the level range of Duskwood should only shard, if the other zones in that level range are not packed, if that zone is over 500 players. If the other zones are not getting used as much then it is a player choice to level in the one zone. If this is the case the zone should only shard once to keep it over crowded so players will need to spread out to the other zones. Sharding should only be seem as a last ditch effort to keep a server healthy.
If many of the zones in the level range of duskwood are over populated then ALL SHARDING SHOULD GET TURNED OFF ON THE SERVER! The server is full. Using the lack of sharding in the low level zones will lessen the desire for players to stay on that server. This will get players to move onto a lower populated server.
Sharding is gross. Sharding is a mess that needs to get cleaned up as soon as possible. I donât see how anyone would be happy knowing they have sharded till they get it cleaned up. At level levels sharding can be expected, but by level 30 sharding should be a clear sing something is wrong. Sharding at 50 or higher should be embarrassing. How can the economy work if everyone is sharding? Those zone should remain limited resources. I canât keep this up anymore, basicly sharding is like pooping your pants and you donât want to do it.
Sharding at levels higher then 30 will be bad for server economies. End game trade items should remain rare, and sharding frees up too much room for farmers to flood the market.
I donât want sharding, but if sharding is going to be used let it be used right. Let sharding be a tool to let servers grow when they would be bottle necked, but turn sharding off when a server gets too big to keep new players out.
Please people lets make some noise to let blizzard know we donât want sharding. We donât want shards to be small groups if they need to be used, AND WE ABSOLUTELY DO NOT WANT SHARDING AT HIGHER LEVELS AT ALL.
If sharding lasts longer then 4 months blizzard really needs add more servers because classic has gotten to be bigger then anyone has expected.
