Reduced Cooldown on Goblin Glider (Engineering)

Found out today that its possible to "reuduce" the cooldown of goblin glider by 1 min and 30 seconds.
When you use your first golbin glider, you simply switch cape with another cape that got the tinker and it doesnt share cooldown with other capes that tinkered!

Might be good for exploring etc?

This might only work with legendary/proc cloaks since it has the 30 seconds on equip thing? needs testing
