Leveling all classes in both factions to 120 in BfA

So I managed to get every class for both factions to level 120 before the Shadowlands pre-patch hits (totaling 24 characters). You might be wondering why I did not just wait until the pre-patch hits to level them to 50. Yes, I am aware that a level squish is taking place, significantly speeds up the leveling process to max level. However, I wanted to at least achieve getting to max-level the (currently) long way before easy mode hits (which is, the streamlined leveling system resulting from the level squish). I have used the 15th WoW Anniversary Event to grind Korrak's Revenge (which is the original Alterac Valley from patch 1.5) to gain levels significantly fast on some of my toons. I also took advantage of the Winds of Wisdom buff (100% bonus exp) on some of my later toons.

Note: Leveling from 1-50 without any bonus exp in Shadowlands should still be faster than leveling from 1-120 with bonus exp from heirlooms and Winds of Wisdom in BfA.
