Use the Engenears cables twice or more!

Requesites: Atleast two engineering chars.

I find out, that the imba Goblin Jumper Cables, can be used more than one time in every 30 mins, even with cooldown.

The thing is:
-Use cables on some1 who have died.
-Trade the item ( that cables with cooldown) to other engineering person.
-He can use that same cables as if had no cooldown.

-If you trade your cables back to you, u'll notice that the Cable's Cooldown its actually a "person cooldown".
