We are also currently at the end of one of those transition periods where people are on vacation until new content comes out. The next major update is expected towards the end of this month or next month, so a lot of players may be back in action soon. School will also be out by then.
So if anyone wants some perspective on the enhance rates...
It takes on average 10,621,060,739 weapons to go from +3 to +20 as posted earlier
So how much time does it take to go through enhancing a weapon till it breaks/succeeds? Maybe you could do 1 per min with all the animations and resets?
So you could do 60/hour. If you played 10hours/day that's 600/day or 220,000/year
So if you played 10hours/day 365days/year and had an infinite supply of weapons, enhance stones and elixirs and all you did all the time you were on was enhance it would take you on average 48,000 years to +20...from +3 without any runes. If you had an infinite supply of +15 weapons it would still take you 4.3 years to get +20 on average....
Since we dont have infinite weapons how about 1 weapon to enhance per day on average (which is still unrealistic). On average that's going to take you 29,098,796 YEARS (29 Million years) to get +20.
Well the devs said that they don't want people to get +20 that easy. And +20 will never be a necesity for anything. They introduced it just so people have some kind of goal, even if it's almost impossible to do. They also said that the live success rates will be different from the test server, so we might get higher rates. They said that you'll never need anything more than a +15 so I don't see the problem with that, people that want to sacrifice hours and hours or a lot of money to get that +20 are free to do so, it's all just for fame as you won't really ever need that kind of weapon.
