That isn’t how Ion explained it. He says layering is a single cohesive world.
Except it decreases competition. Remember the whole point behind layering is to make room for tourists that aren’t expected to play long term. Most tourists will not be reaching far enough to compete with Classic players farming high level resources.
Uhm what?!?! That isn’t how it works. Every single herb is not going to be farmed even on a regular server 24/7. If Bob and Jim are farming herbs in Felwood they are competing with one another and are limited to farming only what can spawn in the zone. If Bob and Jim are farming Felwood but on separate layers, they are potentially doubling the number of resources they can farm since they aren’t competing with one another. Sure, there will be times when Felwood isn’t being farmed on a layer, but there will be times when it isn’t being farmed at all. The point is that when it is being farmed, multiple layers has an impact.
Haven’t heard any other options.
You are missing the point. Layering is able to be removed far more quickly than the server merge ideas that have been thrown out. The problem isn’t the AH on the server pre merge(although it would also be a problem), the problem is that once you merge several dead servers that have been free farmed, you are merging players that have stockpiled massive amounts of resources.
