10 characters need 10 times more gear, 10 times more flasks, 10 times more food. So getting 10 times more ore to sell doesn't sound unreasonable to me.

I feel like Blizzard is happy with this feature, as the bots don't seem to be able to make use it, its only helping groups and raids of real people. Bots just seem to be pathing from one node to the next in singles since keeping them together would be more work.

I'm sure Blizzard is collecting the data and if its too much then its too much and they will change it to allow a fewer number per node. That will just be the normal way of things, to add a feature then fine tune it.

We shouldn't worry.
