This will certainly free up possibilities for some interesting character concepts
though of course while something like Highmountain Paladin wouldn't need anything more than the Charger or Nightborne Druid with all the Druid Forms, others like Void Elf Paladin, Lightforged Shaman, or Draenei Warlock would require more in-game setup whether it be a questline introducing them or setting up something that will allow us to play proper High Elves without using different racials
