Gear Roll Possibilities

As far as I can tell, the following non-exhaustive rules hold true for what can roll on gear. Please do post any gear you have that contradicts any of these rules, thanks.

• No roll can appear multiple times on one gear piece
• Only possible on weapon or accessory
  • Total Damage Bonus
• Only possible on armor or accessory
  • Healing Rune Cooldown Reduction
  • Healing Rune Charge Slots
  • Health Restored Upon Defeating An Enemy
  • Health Restored Per/s During Restorative Respire
  • Dodge Rate
• Not possible on armor
  • All offensive rolls
• Not possible on exclusive
  • Any two of
    • Critical Hit Rate
    • Critical Hit Damage
    • Precision Rate
    • Precision Damage
  • Any two of
    • Bonus Damage Against Bosses
    • Bonus Damage Against Close-Range Enemies
    • Bonus Damage Against Healthy Enemies
• The following exist in separate pools and cannot roll together on gear
  • Healing Rune Cooldown Reduction and Healing Rune Charge Slots
  • Health Restored Upon Defeating An Enemy and Health Restored Per/s During Restorative Respire
• All ability trait bonuses exist in one of six separate pools (3 pools per tree), where gear cannot roll two trait bonuses from one pool (e.g. gear cannot roll Rodent Plague Enhancement and Squirrel Missile Enhancement)
  • Weapons can roll 0-2 ability trait bonuses
  • Accessories can roll 1 ability trait bonus
  • Exclusives must roll 3 ability trait bonuses

Also FYI, Armor Value does actually seem to have small diminishing returns on effective HP. It's not linear as expected.
