But that doesn't change that you're saving cooldowns. Your CotW was not popped initially with all of your other cooldowns, but instead with your Rapid Fire that was popped after many of your initial cooldowns have expired. Mainly your Eng Gloves, and most of your on proc items. That was the "Cooldowns" I was referring to. You're more than likely waiting on your Trinket + Kiril to stack, but it just isn't work it to wait.
As for the Hunter's mark uptime, it's possible it's bugged but you might want to look into it. Many people, myself included, have noticed/reported a bug that is causing Hunter's Mark to randomly fall off during an encounter. Not sure if this is what happened, or is the case, but can't hurt to check.
