trap cooldowns

Can someone help me with what I am missing? I should have a trap CD recovery increase of 75% with gear, passives, ascendancy and support gems but am not even seeing a 50% change to my trap CDs my siphon trap still requires 2.29 seconds to create a single new trap and I was hoping it would be in the 0.5 second range.

The stat you're stacking is cooldown recovery speed, not cooldown reduction. This means 100% cooldown recovery cuts the cooldown in half, 200% reduces it by 66% and so on
