If it wasn’t about comparing reboot to reg server, then everyone wouldn’t be complaining about the lack of those exact features that reg server will be provided with. And involving reboot servers from other regions to support your points seems kind of ridiculous. There are many differences across servers so you can pick and choose which features from which server you would like to have and start complaining about lacking them, because otherwise it would be unfair. And people who assume free-to-play players in reg server have an easy time with the meso market are completely unaware of the economy of reg server and the struggles that most free-to-play players have in it. And the availability for free-to-play players is only there because someone else spent the money for you by buying maple points, so in the end Nexon gets paid anyway.
And the question about what’s fair or not is incredibly subjective, and ultimately up to the developers. Maybe you think it’s unfair that players in reg server who spend money on the game receive more benefits, but from what we can tell the developers don’t seem to think so. People who get upset about why reboot gets a completely different treatment from reg server should think about Nexon’s financial interest. Do you think people will play a “pay-to-win” version of the game when there’s a completely identical free-to-play version available? Or would it be smart to add some differences to create an incentive for people to play the “pay-to-win” version?
Like I said, people here only complain about this because these things exist in reg server and therefore they feel entitled to it in a server that is designed to be a free-to-play cutdown version of reg server. The things you mentioned are all features locked behind a paywall that we do not know any specifics of, which could very well turn out to be a whale feature that only a fraction of reg server players make use of. And if that were the case, it would be open to debate for the developers whether it’s fair or not to give access to reboot servers so easily. If you open your eyes and look at the bigger picture, you’ll see that the majority of free-to-play players in reg server and reboot server are essentially facing the same update. The people who pay get perks because they keep the game running. As it is, people in reboot are already able to do end-game content with key features missing such as bonus potentials and scrolling, which likely have a much larger impact than this familiar revamp.
And like I said, many important details are missing. For example, maybe unique potentials can give up to 9% of your main stat and legendary up to 12% which falls in line with reboot server missing out on bonus potentials, yet people only complain because reg server has a higher tier available with unknown specifics and unknown cost. Also the effect of the difference in max level is yet unknown. Just to give another example, if 3 level 5 familiars can last for 8 hours and the damage done by familiars is negligible then I don’t really see the reason why people should complain about it. Yet here people are complaining about it with important information missing, only because higher levels exist in reg servers behind an unspecified paywall. And about rerolling potentials, what people seem to miss is that all the available lines per tier and the chances to roll your desired lines are still unknown. Maybe it is a massive time sink, maybe not so much. It all depends on the details. And perhaps the vast majority of reg server will use red familiar cards or perhaps they will farm like reboot players. That all depends on pricing. With all this information missing it’s too soon to say whether it’s a good or a bad revamp, but here people are complaining about missing features that you don’t even know how much other people will have to pay for.
Reboot demanding to get whatever normal world whales have to pay for, but for free, didn't work for the Re:Zero medal, nor for Frenzy Totem or anything else that is hard-locked behind cash in normal worlds. In my opinion, It will likely not work for Familiar items either, unless Nexon makes them not-that-premium for reg too.
