Default Ranking-Up System is indeed a great idea according to me because there are many people on this forum that contribute good quality and constructive posts but aren't ranking up because they aren't receiving enough merit.
The meritocracy is saying they've received enough.
I'm also failing to see how this proposal is any better than the current system. You do realize that the merit system was introduced to make it much harder for shitposting idiots to rank up, right? If you make it a function of just time, then we're right back where we started. We can discuss this all day long, but I don't think Theymos is looking to go back to the way things were.
I also think many people here tend to think their posts are much better than they actually are. Most posts nowadays are just broken-English garbage that no one wants to read, hence why you're seeing most users not getting any merit and not ranking up. That's how the merit system is supposed to work.
