Well you have to have the farming expertise to maintain enough resources to remove the obstacles. You also have to have superior time management to manage your builders so you are able to remove them. You have to have ninjalike tendencies to keep your device secured so others don't pick it up and chop your trees down. Finally you need to have pinpoint accuracy to be able to "touch tree, remove".
Since its Xmas today (in Australia) would the Xmas tree give any good stuff, or would I have to wait until Christmas in America?
I hope we can keep them, but wondering if they're going to revert to normal trees after Christmas.
