I've also personally used IPS4, and it's been great. Not only have I had close to zero issues, but it runs amazingly. As Aleos just mentioned, the current forums are extremely buggy from years of adding, removing, and modifying things.
Your lack of faith is surprising and I have no idea where it stems from.
Then you start bringing in completely unrelated points: The last downtime you mentioned happened before the change in administration, and Aleos has been extremely active since taking up the position. Not only that, but the market place was removed due to a huge controversy regarding the payouts; I'm frankly surprised you're either unaware of it or pretending to be so. While I do agree that rAthena could be doing a better job at community building, I do not see how that affects this decision in any way, shape or form.
Make suggestions, write 'em out, post 'em on the forums. I'm sure the staff and community will be glad to hear you out. But do it with time to spare, under the discussion forums, not as a last-minute reply to an announcement.
And this isn't me replying as any sort of authority figure, this is me replying as a standard member of the community who would also love to see it grow and prosper.
