*I tried to test them all but I am sure I missed a few. Sometimes the synergy between two mods can make a mod more powerful, but often it threw unnecessary levels of complication or more errors.
I've chosen a variety of mods to suit playstyles and Classic philosophies, from bare-minimum mods to feature-rich addons that you can tweak to your own exact specifications. This is my opinion about what I found to be the best addons for helping you level your characters in Classic, whether it's your first character or part of a stable of alts. While "Best" is a subjective term, in this guide, I will dig through the best addons for leveling in Classic and indicate ones I consider essential.
