In normal servers, we are currently limited to buying 3 buff freezers a day with meso from the Matilda NPC. Beyond this, we have access to 1 (one) buff freezer a month from the Reward Points shop, and any more freezers than this must be bought with NX.

Compare this to the systems in place in Reboot, where players can buy unlimited buff freezers with meso; as well as in Korean Maple Story, where players can buy basically unlimited buff freezers with RP (mileage).

GMS obviously does have Battle-roids, which neither Reboot nor KMS have and which obviate the need for buff freezers in the first place. However, Battle-roids can only be generated from lootbox systems like Philosopher's Books and Marvel Machine, and are rare enough that even when resold in-game, they are typically out of the price range of the majority of players.

The reason I bring this issue up is primarily because of the need for buff freezers in bossing scenarios. In the course of a week, a f2p player can accumulate a total of 21 buff freezers by buying out Matilda's stock every day, but in the course of running the game's weekly bosses (including any possible practice runs, or re-dos in case of a failure), it is very easy to die more than 21 times. In the past, buff freezers may have been more of an optional item, given the lack of important buffs to save in case of death; however, in the current game, the difference between keeping or losing your buffs after death may be the difference between your or your party's failing or clearing a boss. In my own experience, I have seen many players struggle to clear bosses that should be within reach for them only because they have run out of buff freezers, or else shy away from attempting bosses altogether because they would rather save their buff freezers than potentially waste one on a practice run. In these situations, it is disheartening that I can only tell them they should take a break from bossing for a while to build up a stock of freezers.

In effect, the limited access to buff freezers forms a "soft wall" for many f2p players that discourages them from practicing or participating in any relatively difficult boss. You can say that if a player does not want to spend either real money or else tens of billions of meso on a Battle-roid, then it is their responsibility to die fewer than 21 times a week. However, the fact remains that this system is very unfriendly to a large portion of the normal server playerbase and that allowing players to buy more buff freezers with either RP or meso would open up more opportunities for them to engage with all the content the game has to offer.
