First of all, let's not kid ourselves, this game IS standard Asian MMO trash, lol. I'm sure we'll have plenty discussions on that topic as we play.

I recently got laid off when the restaurant I was working at went under, so I'll have plenty of time in October as well, as I temporarily suck on the governments teat for a much needed vacation.
Anyone who does something because a streamer says so is a retard. People are going to say the game is trash anyway. Much of that whining is performative these days. If someone plays a bunch of alts just to progress at a certain speed, and they don't find that enjoyable, how the fuck is that my problem?? Streamers are still gonna say "you gotta do this every day, and this every week, and do this, and do that, and use this build, and make sure your monitor is facing east etc etc etc etc etc" They literally make up shit to say just to be able to make more vids. It's nauseating.
The game already has a dozen different grinds in it, what's one more? You're overlooking the fact that the reason "having" to play alts is such a pain (for some) is because the game has too many systems to grind for. That's the real issue.
I used alts to make extra gold in Lost Ark because it was an efficient way for me to progress at the speed I wanted. I never gave two fucks about what anyone else was doing or compared my progression to theirs. When it started to feel more like work than fun I stopped doing it. One of the drawbacks of being a sane adult.
TLDR: This game will be dead in the West by the end of the year, whichever choice they make. I'll put money on this.
