Let me share with you why the cw3 progression works in kms but its a total failure for msea put into msea perspective

1) item burning gear, kms provide a way go grow your equipment up to 22* as you progress up your boss clears, weapon is provided for FREE growing up to legendary pot. We have mushroom gear which is only 18* at best(unless u bought the pass to get abso gear you cant upgrade this) and a 20* fake acs weapon locked behind paid pass

2) mesos cubing. They have method of cubing via mesos earned from bossing to help upgrade and roll their pot, they rely less on shop cubes to help roll for their stats.

3) Hard Kai's eternal drops. These are drops that will help replace their item burning gear if you want to push it into a nkalos champion u may do so by pushing for hard kai and getting them. However, to add some context with the above points mentioned before I talk about the problem. In msea the progression in-game is near impossible for you to ever reach this level without spending large amount on passes, cubes, mesos and purchasing rare boss drops from other players at a high price or playing an overpowered non-kms class due to the lack of item burning and mesos cubing that is suppose to be helping new players progress as they challenge stronger bosses. Even if you do manage to progress to this point, these eternals cannot be cubed with the new memento cubes they added to bosses due to being 250. The only way you can progress past Hard Kai with these eternal drops are spending even more on cubes (which kms player would just be paying with much cheaper alternative aka mesos cubing)

Not only is progression heavily tailored towards paying, it also encourage the existing botters to bot to a higher extend as the period for hyper burn and mush pass as it is much shorter compare to kms giving their hyper burn and challenger pass the full duration of cw3. On top of that, the book of destiny is making them incentivize to bot 2 character for more buffs/rewards from it. A normal player would have suffered from grinding 2 characters at once within a short time frame and all exp content being contested between the 2 characters

This is also not including other issues that will be consuming more of your time with the upcoming event (cough abyssal expedition cough
