Hard to take you seriously when you complain that "battlepasses are psychologically stressful".
It's actually astonishing that you've made it in life this far.
Can tell OP never played a game with a season battle pass.
You are not punished for taking breaks. It's an aesthetic item that you don't need. It has a cost in playtime, feel free to pay it or not to pay it.
Let's say you see a pair of sneakers in a store that you think are really cool. You already have enough shoes at home, but still it would not be a financial burden for you so you might as well, but you still decide you'd rather not spend the money. You end up with no new sneakers, but your feet are plenty covered anyway. Have you been punished?
I don't really mind the fact that the coffer's at rank 25. The requirement to get more Trophy Crystals after 30 DOUBLING feels absurd though.
On the topic of past rewards, the fact that the only thing currently buyable from the Feast is essentially just participation rewards from it (which Series Malmstones also are) i don't see any issue in making the rewards of past ones buyable later on at an exorbitant price.
5k for the emote/first framer kit, 10k for the mount/second framer kit, and 20k for the attire coffer sounds reasonable, and if you missed all of last season, you'd need to obtain 50k Trophy Crystals.
Because of technical limitations, there's a limit on Trophy Crystals to only 98k per season. (Yes, this is real. The "Infinite" caps at 100.)
Completing a season to 30 gets you 28k. This means if someone wants the "good stuff" from a past season, they're going to need 200k series experience in the current season. This is still extremely offputting to casual players, but does allow for people who want the gear but missed out on it earlier to get it through sufficient grinding.
What you already said is what you were saying but hoping that using strong words like "threat" and "coercion" tricks the reader into thinking you are crusading against evil. It's not a threat, no one is smashing your car windows or taking away your medicines if you don't get Rank 25. It's not coercion, you can choose to work for the reward, or you can choose you don't care enough about it. And it's definitely no amount of small time, unless you voluntarily make it small, by taking breaks. You can comfortably get to rank 25 by the end of the battlepass by averaging one game of CC a day, and they last less than 5 minutes.
For developers to tickle that FOMO you were talking about, the FOMO needs to exist, and it looks to me like you are more predisposed to it than many others. And it's the same FOMO that makes you fail to realize you are responsible for taking what's on offer in the time it's on offer, or to let it go.
Go back to my sneakers example, but this time it's limited edition sneakers. Would you say Nike is coercing and threatening you because stock will eventually run out?
Spam CC for a day and get your reward track maxed out, it's not that hard cmon i do it every time...
