WoW Classic's racial abilities are easy enough to understand. Some races,
such as Undead and Night Elf, are clearly more geared toward PvP
content, but you will probably have the same fun with any class and race
combination (unless you get a little too used to Will of the Forsaken).
It's important to keep in mind while reading through this guide that
ultimately, you should choose whatever race and class combination you
want to play. Meta gaming WoW Classic only does so much, and it's not
like you're about to tackle the hardest content Azeroth's ever seen.
You have a little more to think about in terms of race as a PvP player, but
if you played way back in the day you probably already know which race
you want to carry you to victory in contested areas.
