Resto Druid haste cap

I have been looking for several rounds and that a hasty resolution, I confused Druid tbh.

First of all, the greatest common factor activated for 1.5 seconds, we need to get it 1sec, the majority of the population rate of 33.33 percent in favor of hasty we need is not it? Some people say that 50% of the reason, but 0.75 seconds is not it?

Earthmother gift also gives us our 20 percent of the white-hot rush of all we need is 13% haste remainding right or what I am missing it?

Btw remmember 32.79 haste = 1% reduced casting speed, it does so% to the greatest common factor or less?

At the same time, if we only need the remaining 13%, 427 more than we need to rush right? (May 5 with gifts and there is no other rush earthmother enthusiasts / professionals oxygen-free copper)

The formula to calculate the gain from haste is:

modified cast time = 1/(1+(haste%/100))*original cast time

If you use 1.5s as the original cast time you need 50% haste to get to 1s

1s = 1/(1+.5)*1.5s
