D&D General Higher Level = Greater Complexity = Slower Play

[Ogre Mage]

I personally have found mid-Tier 3 is about my limit. Beyond that I start getting overwhelmed by keeping track of everything my character can do as I always play spellcasters. I did not enjoy the small handful of times I've played in Tier 4.

Probably my ideal campaign would run from Levels 4-14. That is a good span to experience a lot of character growth.
