The Collector now deserves an exact page
Current official and public-demand surfaces no longer justify leaving The Collector only as a broad wiki mention. This page covers the safe role-first answer without inventing exact trap or balance data.
The practical answer is that The Collector is the high-cost trapper route for players who want setup pressure, area denial, and map-control decisions instead of the more direct KillerKyle or Crash Dummy path. This route exists because players search the character directly, not only the generic Entity roster.
