I think ranked people should be able to mine spawners they placed with silk touch picks. Not wild spawners you find in the grid but a spawner you placed. zRinne was talking to someone about how they wanted to move and spawner but she couldn't because it was a grid spawner. Well i think maybe supporter+ should have the ability to silk touch placed spawners.
I disagree with you. If certain donators can mine spawners they will do their utmost to find and get as much spawned as possible. They will destroy a lot which makes it more difficult for non donators (or donators with a lower rank) to find and use spawners. The economy may get worse as well since players without that rank are willing to buy spawners. Donators will most probably sell them for insane amounts of money.
Not the ones in the grid. Say i place a cow spawners in the wrong place. Then i can mine it with silk touch. Not the generated ones in the grid.
I thikn it is seeming zRinne couldnt move a generated spawner that someone asked her to. So its possible.
I don't mean the plugin as mining spawners in general. I mean the plugin as in not allowing players to mine the spawners in the wild but allowing them to mine the ones they receive (voting).
