The most common use of Readiness is to reset our Rapid Fire ability and allow us to use it multiple times during a boss fight. That's right we can use our Readiness ability to get anywhere from four to six depending on the length of the encounter.
There are two schools of thought on how best to use Readiness and Rapid Fire in a raid encounter. The first method has us synchronize the cooldowns of these abilities by performing the following sequence.
The second method method focuses more and getting additional Chimera and Aimed shots off sooner, but you're Readiness and Rapid Fire cooldowns will not be in synch.
Some general thoughts. Don't just focus on Rapid Fire. If Rapid Fire has fallen off, but Chimera and Aimed are not on cooldown, you'll want to wait until you can get both those abilities on cooldown before using Readiness.
Also, you want to try and stack Rapid Fire with as many procs and abilities as you can. Using Rapid Fire at the start of a fight ensures that the majority of your procs will be cooking in conjunction with Rapid Fire.
After Readiness and Rapid Fire come off their three minute cooldowns, you'll want to assess things before repeating the process. Maybe it makes sense to pop Rapid Fire right then and there or maybe you've got some things coming off cooldown and it's worth waiting a few seconds. Whatever the situation, it's certainly not worth having one fewer Rapid Fires for the sake of stacking buffs.
There is a lot of nuance that comes with the Readiness ability, but we love it and we use it early and often. How about you guys, when and how are you using Readiness?
