Explanation:This mechanic was first time introduced in octopus boss from 2019 and was built around to give everyone same fair share of chance to get exclusive event items, nobody ever complained about it due to equality it has offered for everyone. Meaning no skin crates was dropped inside the chest as it would remove value to the exclusive items and this is very bad system to use. Given with the explanation, ill count couple reasons why this old system has fatal flaws.
Reasons:
1. Since you already get rewarded skin crates in special crates once you own the mount, theres no purpose buying it with tickets, and buying the mount with tickets would ruin the "purpose of being exclusive", which doesnt changes the the fact that people will use this as poor excuse to prevent others grinding for the sake of cosmetics that they wont use. Ruining one prupose of a feature can and will cause a domino effect on different multiple features makinf them meaningless.
2. It has been issued that players with jetpacks can cheese out the chest by being above the gates which hasnt been protected properly, preventing players that dont own it able to be rewarded, this also doesnt changes the fact that people will use it as an excuse for "easier grind". There are people who dont have any mounts yet, this shouldnt be a race between he ones who already own it and who dont, this should be only be between who dont have it.
3. As mentioned on first reason, mounts never were sold on tickets and is not good because skin crates were never considered "exclusive" either, so why should skin crates be on sale if they are as rare as mounts only if you could achieve them through special chests.
4. Personal perspective: Most higher ranks I met have rated the mount as low tier, though in their opinion may be valid with grinding the skin crates, it just doesnt justifies enough grinding it where there are still people who are trying to grind for a mount over grinding tickets for skin crates which makes this event (and future events) not beginner-friendly and fresh players wont be able to enjoy the game which wasnt the first time some of them experiencing this. This isnt healthy for community and for the game, and it deserves better than this.
Conclusion: The current event chest mechanic devaluates exclusive items that cannot be obtained ever again, due to various complaints of nof choosing to make old mounts available again, it has come to conclusion that the best solution would be to make it more friendly to lower ranks and disable any kind of advamtage for higher ranks as it is not rank equality friendly and causes backlash from both sides.
