Make a tank item that reduces cooldowns by 3.5 seconds on a kill/assist.

Hey guys, I was just thinking of items to make tanks more useful. Maybe this could help. I said 3.5 seconds because I wouldnt know what would be just the right amount to be a balanced item. Unless properly tested. This wouldnt do much on tanks such as Because they have weak CC and long cooldowns.

But someone like It would obviously be very good

3.5 seconds sounds generous enough to me because tanks stack CDR anyway

The stats could be something like

500 Hp

30 armor

30 magic resist.

building out of + + that builds into (as it is on the PBE)

With the passive of course giving 3.5 seconds off all cooldowns on a kill/assist

What do you think?
