Looks like they’ve either added more levels, or have added some sort of reward after leveling up through 100. im gaining experience again and im hero rank 100.
Yeah, noticed that too. . .
Yep its favorable for us maxed HR 
Just level up to 101. Tickets increased +1
It is possible that there will be no cap of level, but leveling up only increases the ticket cap.
I confirmed in other threads that team cost will increase as well.
Level cap is 150
Leveled to 100 today lol
Well its favorable for sotf incase you need a ticket refill
