I have a question regarding:
1.what's the real reason for using both chasmal armor and ebon armor if they are similar procs?
2. Why are both used at the same time, if their proc does not stack?
3. difference between haste and cool down
4. What is haste and what does it have to do with all this?

If anyone knows I will be very grateful since it has not been clear to me.

-Regards-
