For me there are no big problems with the p2w, cash shop or bots on official servers because I mostly play solo now. And I play only PvE. I'm not really competing with other players, so don't care that there are god geared players around. I want a good economy on the server of course.
For me the main problem of the official servers is that they simply disappear even before the private servers. In my country, the official server existed for 10 years, then closed. Now we have opened a new official one, but without transferring the old characters. And they can close it at any moment again.
If they guaranteed by the very fact that this is a super puper Gravity corporation and their servers will never close, even if online drops to 10 people. Then I agree to play it and invest time. But they don't care about people, only their revenue from the server, stable or falls
