Dark oak saplings at the spawn store are wayyyyy too expensive. In order to plant a single tree for each type, you need: Oak - 0 grass Birch - 3 grass Spruce - 3 grass Jungle - 4 grass Acacia - 6 grass Dark Oak - 24 grass. The reason for this, is because you NEED 4 saplings to grow a dark oak tree. This means that you need to buy 4 dark oak saplings for 6 grass each. While dark oak is objectively the best wood type (don't @me) it should not cost literally 8x more than birch to plant the tree. 6x more than Jungle, and 4x more than acacia. The reason for this problem I'm sure is just an oversight and thinking of the cost as being "per sapling" as opposed to "per tree". In order to get infinite saplings, you need to be able to grow the tree first. And as stated before, dark oak cannot grow with only 1 sapling. The solution? When buying dark oak saplings from the shop, they should come in groups of 4. This is because you simply cannot do anything with a single sapling, unlike the other trees. While yes, spruce and jungle also have 2x2 variants, they can still be grown with a single sapling. Thus not causing the price to be multiplied by 4.
Never knew dark oak saplings had to be arranged in a 2x2 grid. If there are those like me, they are sure to be disappointed by this shop purchase afterwards.
Basically this was my only drawback against the suggestion, while other saplings are exponentially cheaper and I feel like the price should be brought down from 24 per sapling to 24 per tree, there are many other places to buy saplings (ex. Haberson, GucciShop, etc.) the server as flaming mentioned encourages trade so while I will support, I feel like its' most likely insanely priced for that very reason.
