i have no ideea how the hell you did that , but whatever. I rushed ex stage in both part of events (i think i was top 150-200 of players reaching them) and i also invested a bit of stamina in them. Quite active (duh , i was on every day ) and didn't lost much stamina overnight either since i generally sleep 5-6 hours (and that's how much it takes for my stamina to charge). I barely reached 25 , and i can't do more then 1.5-2k per day. I have no ideea how you guys did it
