It doesn't actually SMN is one of the only classes that keeps all three spells, sort of like how BLM gets 2 thunder spells (one an aoe, the other single target) because they have different uses. If Ruin was thrown out the tooltip for Ruin Mastery would only mention Ruin III especially because R. Mastery is learned at 62 and Ruin III is learned at 54. If so they would've moved R. Mastery down to 54 with R. III
