Because this is the typical client requesting feature without one and a half of an insight to how it works, I'm gonna so respond to this as if I'm talking to a client.

Your idea is infeasible. Why? Chilly's profit comes mostly from ad revenue because most players don't have access to a credit card or simply refrains from paying due to the fact we have Free Trial Tickets for skills and characters that require real money to purchase. The ticket can be grinded, therefore somewhat eliminating the needs to buy. Plus, players in RPGs would usually specialise themselves into playing a certain char, or "maining", further reducing the chance of actually buying anything. But what if you want those contents without paying? Say hello to the dark side of modding and APKs. Despicable, but it gets the job done, and money from ads would go to the modders, not the devs because they too needs money. Don't believe me? Crack open a few mod APKs and compare the ad modules to the original ones, do it for several games from several releasers.

And how can you be so sure that people would welcome this idea? Where is the survey? If you point me to a post with 50 comments I will gladly flip the bird and call bullocks. That's not a true representation of the community if want to speak statistics. That's biased, and biased sample is a giant fuck-you to any kind of statistic. If you want a convincing survey, you don't offer them a yes/no, give them a rating table 0-10 on your proposals, etc. I'll leave this to you.

That's the player side, now we get to the corporate side. As mentioned above, Chilly's main income source is ad revenue. Keeping the studio afloat is hard enough when this revenue fluctuates due to ad view counts being a human factor, plus, Soul Knight is their flagship game, their lives depend on whether or not the game floats. With all that struggles (salary, PR, servers (they have servers for WHR, and before you jump the gun, they will probably not use those due to the horrendous latency)), they will probably not wanna employ more servers.

Servers. Ah yes, here comes the servers. If you want smooth game experience, you will need multiple servers located throughout the world to keep the ping down. If you want to see horrible latency, look at Super Mario Maker 2. Ping is one thing, handling the load is another, especially at launch: You are talking DDoS-tier traffic spike which can easily collapse a server if it cannot handle the traffic volume or cannot process ot fast enough. Plus, this is real-time shooter, packets will be coming every single frames about where you are, what buttons you are holding, what direction, what weapon, what are the pet's positions, etc. And all that, all that, is that if you ignore the fact for each game, the server will have to simulate the game itself to deliver back to the players for synchronicity. And anti-cheating. Oh god that shit is annoying. Cheating ruins the fun, ruins the games, and detecting stuff like that? Good luck implementing that on low-levels. Even games like PUBG Mobile struggles with hackers, and that game is big-corp. Chilly is a small studio.

Sure, report hackers, trolls, AFKs. Well, cost is here again. You have hire people to look the game, the report, watch thhle replays and determine the hammer strike. "Just implement Machine Learning™ or some algorithm" you say, I say no. How do you define trolling, and tell it apart from stupidity? Maybe their connection dropped, that's why they aren't moving. Referee is not a job a machine can automate, and training the AI needs data. Where is this data? We need mutiplayer. Catch-22.

And ALL THIS, is if you ignore the bugs in Multiplayer are having right now as u/BOT_4K mentioned. Bug fixing multiplayers is hard because the one thing they need is the trace logs, and the packet dump, and the memory state so they can debug. And sadly, all of these are not ever delivered because all you know is complain. You give them nothing to work with, and you demand they fix it? Much wow.
