My Top 4: 1. A defender Titan without Saint-14 isn't worth very much. This Helm Kind of defines the defender in a way. 2. Don't Touch me gauntlets for the Hunter, regardless of which subclass is a close 2nd . 3. Obsidian Mind Takes the voidwalker to a whole new Level in PvE. 4. The Ram for PvP. You all Know the Stories about the Ram. All other exotics Are either good, Not so good, very situational or basically useless.
