I feel like the items available in the points shop right now are really only useful if you are making a mob grinder, and not everyone makes mob grinders. I think it would be really cool if some crop farming related items were added to it, such as mcmmo and sell boosters, fortune enchanted books (higher than what's already available), and farmland (pre-hoed dirt). This would also encourage people to vote for the server more.
Selling farmland blocks is an interesting idea. We'll look into more items for the pointshop, thanks for the suggestion.
