WoW Classic Race & Class Comparison Tool
This tool lets you quickly compare race and class combinations side by side - it lists each combination's racial traits, base starting stats and other useful info. Hopefully this will help people who are still undecided on what they want to roll for a new toon, and for those who want quick info for theorycrafting.
If you want to calculate exactly how much extra DPS, Armor, Dodge, Mana, Crit, Block etc. is provided by the differences in base stats listed above then you can use the basic stats calculator tool to do this quickly and easily (open it in a new tab!).
