idk since when this rumor has been around. so does doing alchemy after maintance is more rewarding or is it just a placebo effect?
This is true for pretty much every roulette on official servers BUT not for our server.
Official servers have a server-wide limit regarding good items from roulette. This limit only resets with maintenance.
We removed these limits in almost every case and replaced them with time-based limits.
Example: A certain item can be received 100x times from roulette. After the limit (100) has been reached, there is a cooldown for 12 hours.
After 12 hours have passed, the item can be received 100x times again from roulette.
This change was introduced so players from all kind of timezones have chances to obtain good rewards.
The official system is biased towards players that are online when maintenance has finished.
