Let's say hypothetical spell X was buffed during vanilla from 400 damage to 500 damage and then later to 600 damage.
If we assume #nochanges any of these three numbers would be okay to pick for that spell right?
Let's assume that 550 is actually the number that makes that spell the most balanced. Blizzard would then not be allowed to set it to 550 but instead leave it too strong or too weak?
