There are a lot of survival games out there, including this one, that require you to remove the stump of a tree and replant it so the tree can grow back again. I don't see the purpose of this when realistically the tree would most likely grow back from the stump. Therefore it's a surprise why so many survival games add this senseless and time consuming task. Stump removal should be something you do if you don't want that tree growing back again in that particular location.
Another thing to note. Many servers, if not all, have rules that require players to remove their stumps because it causes lag. Having stumps grow back into trees could potentially fix this issue.
