Agreed with
@coolzombiee here.
The design team works very hard on all the cosmetics they publish, as well as the developer team being heavily involved in making them work in-game. Every employee needs to get paid for their hard work, which is possible because players donate to the server in return for cosmetic items (bundles) and perks (ranks).
If you don’t want to spend money, invest time into the free rewards you get for finishing lobby parkours and seasonal hunts. They’re just cosmetics. If you can’t afford it, ask to get minecoins for your birthday or a holiday, or get a job and earn money, the same way the designers do by working hard on these cosmetics. As a final option, you can always enter giveaways.
