Have you played a job with charges?

On COR you shoot one QD and have 1 min recast on getting it back, then you shoot again and have 1 min 58 seconds until you got both back. Which means that once you can shoot 2 times, then every future shot will have to wait 1 minute. Until you take a break and wait 2 minutes for both to recharge.

What you probably want is separate BP timers. So that first you do 1 pact, and have to wait 1 min on that, then you use another pact and have to wait 1 min on that and 58 seconds on the other one, meaning 2 pacts available in 1 minute.
