It doesn't necessarily work quite like that. Although true, the implementation of a suggestion like this would violate Minecraft's EULA, the EULA enforcement system doesn't operate so swiftly. In what I've observed over the course of the past year and a half, Mojang's enforcement of the EULA operates primarily on the basis of violation reports (
https://bit.ly/1OCPquW). I've also witnessed that such enforcement has almost exclusively been emphasized on medium to large-sized servers and networks. Yes, obviously small communities have been affected by the EULA to a considerable extent, but I do think it's important that we keep in mind that Mojang doesn't have a huge team of employees scattering the realms of Minecraft like vampire hunters looking to feast on small communities that may seem a bit more reluctant. That simply isn't a viable way of conducting business with such a vast number of different networks at large.
I personally would not recommend completely disassembling the compliance that MassiveCraft has already established for the EULA, but that doesn't mean it is not something to be considered, especially when taking into consideration the current financial state of the server. If you take a look at the stores of just a few large networks that focus primarily on factions-oriented gameplay, such as CosmicPvP, SaicoPvP, Jartex Network, GotPvP, Desteria, etc., each of them are currently in violation of the terms outlined in the EULA and have been for months with little to no intervention from Mojang in the past year, despite the fact that each of these networks maintain a playerbase of anywhere from 400 to 2,000 players online at any given time. It's also unofficially worth noting that Mojang does pay attention to its community, and there is no doubt they have noticed the crippling impact the EULA has made on Minecraft communities alike (enforcement has most likely weakened for a reason). After all, that takes us back to the statement regarding violation reports. It's evident that the playerbase of these networks are satisfied with the donation packages these servers offer, otherwise they wouldn't keep coming back and they would also be filing violation reports against the severs' stores. Obviously, if a server were to provide packages that are too pay-to-win, it wouldn't go over well with the playerbase and I know that it certainly wouldn't go over well with Mojang once they receive a ton of violation reports regarding the matter. The key is to provide a store and packages that are balanced and not too pay-to-win or advantageous, but also enticing enough to persuade the community into donating more (as many of the above stores have exemplified).
Not that I agree with the suggestion posted on this thread specifically, but I do want to recommend that the Premium features be reworked/adjusted when the time is right, especially if this server wants to grow in financial capacity. That doesn't mean, "add a bunch of pay2win perks that ruin the economy." It simply means to review what is currently offered, try to improve on such, and offer something a bit more enticing. I must emphasize that it can be achieved either way, however. Compliance with the EULA or non-compliance shouldn't be a decision that is made by the community, as it is ultimately the owner who is affected. I've seen players time and time again make the statement, "I'm not donating for the perks, I'm donating to support the server because I've been here for ages and I want to see it succeed!" I believe the statement in and of itself is a lot more telling than originally realized, because wouldn't you want such a dedicated playerbase to be rewarded in a beneficial capacity, as a show of appreciation? I plan on donating to support the financial needs of MassiveCraft and its new endeavor regardless of what is altered or offered, but the idea of members with literally
years of devotion and commitment to this community being
charged monthly for just a few simple cosmetic features that truly have no real benefit, special value, and individual appreciation or recognition seems like a slap in the face to me. I believe it's time that MassiveCraft re-evaluate its donation store and try to improve and advance for the betterment of the community, to stay up to par with changing times and server competition, as well as maintain the same standard that many other servers afford to their playerbase. Either way, if MassiveCraft were to grow in capacity in the future, you're eventually going to want to entice new players to donate. Not all new players will be as devoted as oldies like us and as willing to give from the heart.
