I know that 1.9 and 1.10 dont really apply to skyblock, since you can't go to the nether or end, but it would be nice to grow chorus to make purpur blocks (1.9), or store bonemeal in bone blocks (1.10, see Logdotzip or other news videos). Also these would affect the economy positively because of the added crop, and blaze rods have another use (end rod crafting). Bone blocks would also be able to store more bonemeal to sell more efficiently. Purpur blocks in 1.9 look more appealing to some players more than cobblestone, which can boost business. These are also the crafting recipes for the new 1.10 blocks. Also visit to see more about the new update and the benefits.
Are you seriously suggesting going to 1.10, when: a) We aren't even fully 1.9 b) 1.10 isn't even released c) I just wanted a third option
