Because there is no longer a vshop/meepshop, I often find myself trying to buy or sell items at chest shops. This would be okay, but the towns with the larger chest shops tend to have grinders. My computer slows to a crawl until I get out of that town. I can only imagine how bad it is to live in a town like that. Grinders are used by having players swat at the feet of harmless mobs. I think spawners meant supposed to be fun, but now they're boring. If they were only place-able in the wild, then a sense of danger/excitement would return, as the player would not longer be in the safety of a town. Anyway, my point is that towny grinders should no longer be permitted, and I do like most of the suggestions by you other players.
I think that spawners should remain accessible to Elite+, but they should not be place-able in the towny worlds.
