There are several good resources that show all heroes in the game and their stats,
(my fav is https://empiresandpuzzles.fandom.com/wiki/Category:Heroes )
(also New! All Updated Hero Rosters is great, I would like to get that in a spreadsheet so I can analyze it better than pictures)
however they always show them at MAX (so 4/80 for 5*, 4/70 for 4*).
Is there somewhere that shows each heroes stats at each tier - unleveled, 2nd, and 3rd as well as 4th ?
If not, someone in the community should start amassing screenshots of each hero at each tier as it would be very useful to compare and see who to level next.
