Seasonal resets is what keeps bringing ME back!
With every change base game updates and seasonal content brings, I play a class with a new build I haven’t mained before. Some seasonal changes alter builds significantly and even create new build designs that didn’t work well before.
I know not everyone enjoys seasons but I love them and 100% would not be coming back to Diablo games without the changes that new season brings. It would just be too stale for me.
