Instead, I've arranged the combos from most popular to least popular class, as determined by the D&D Beyond list of most popular character classes and races.
So I am not discussing why humans are the best race to play.
Also, in 5e, Humans are the most advantageous race of all with a +1 on all their statistics. In my search for the best combos of race/class, I found a great deal of debate and very few facts, so these combos are based, in part on game mechanics, but mostly on my own opinion. Please also note that I am using all the expansion races. Please note that I am not including multi-class or specialist classes, only the basic ones. That is perfectly progressive, and so, to celebrate this racial diversity, I present to you my choices for the best race to be played for every class in D&D. Monsters who previously had room only as NPCs, now can become part of the adventure permanently and become the star of the show. The 5th Edition of Dungeons and Dragons has introduced some fabulous chances to play different races as Player Characters.
