The jumpship trophy is like 95%. The percentages I feel help shed light on the actual retention are (and this is by no means perfect, but its the most accurate we can figure): [u]Vanilla[/u] Fully upgraded legendary - 25.5% Fully upgraded exotic - 22.0% Vaunguard rank 3 - 26% Fully Upgraded subclass (mean across all) approx 18.3% Crucible rank 1 - 27% (clearly PVP is NOT why a lot of people bought the game) [u]TTK[/u] Subclass quest complete (mean average) - 15% Court of Oryx quest complete - 13% The Taken King Quest complete - 22% That potentially means that the number of active players since TTK dropped has actually been well under 1M!!!!! This would drop the overall retention rate to under 10% in 1.5 years.
