"2 Charges:
-Use Deterrance once, 1 charge remaining, other charge will start its own 3 min recharge
-Even if you use the 2nd Deterrance charge 2 min after the first, the first deterrance charge would only have 1 minute CD left¨
-Once that 1 minute has passed, you'd have 1 Charge of deterrance with 2nd charge being on CD for 3 more minutes.
It's a very simple mechanic and very well designed to provide a choice for intelligent play
Other classes also use this Charge mechanic:
Warlocks; Conflagrate, Hand of Gul'dan
Warriors; Charge(talented)
Monks; Roll/Chi Torpedo 2 or 3 charges(depending on talent choice)"
