Of course, but that is a very specific, different condition that only happens rarely for a few seconds, at very high crit chance, and not what we are talking about, nor what the aithor of the thread asked. If the next Bestial Wrath is already off cooldown while the previous is still active, you can wait until it ends even at 2 charges. But read the comments above, they are assuming that half the Wild Call procs get wasted every time, and no one mentioned that overlap at all. They just said they sit at 1 charge through the entirety of Bestial Wrath, without context.

1 Bire Beast or 32 Kill Commands? What are you smoking? An average raid boss fight lasts between 3 and 8 minutes. 32 Kill Commands cost 960 focus to cast and takes 32 GCDs to perform. What kind of ludicrous scenario does that amount to 1 Dire Beast?
By the way, zoo build around 40% crit procs Wild Call approximately once every ten seconds. All the math is pointless if you start with a wrong premise.
