Hello, I think similar suggestions already have been posted multiple times, but it needs a bump.
Every season there are several sets/mechanics etc that are based on enemy stats, for example undead set this time or emperor in s3. But we never know enemy stats in PvE so the only approach to improve setups is testing, but testing isnt much fun because of rng, time consumed and limited gold.
Please make a tab in enemy information screen that shows their base stats, would be easy to implement and a big QoL improvement.
