I actually doubt this statement. My guess is large numbers cause excitement up until they become impossible numbers to really comprehend. It shows power gain over time and creates cool screenshots for people. A LOT of psychology goes into gaming and if small numbers were more fun to the vast majority I think you’d see it happen in more games.
Personally I just inherently interpret damage as a % so… I am bad person to have this work or not work on, heh
Re-scale it but I wouldn’t remove it. The Paragon Board is one of the better aspects in D4 imho. It is something interesting to mess with and allows for a new way to provide nerfs and buffs through tweaking those numbers and introducing new boards.
