Based off of your loose knowledge of math assosicated with the class, mastery does trump haste point for point as most of your big damage is done with instant casts under the effects of FoF, so I only have 1 thing to say to you.
You are wrong, you do PRE POT fights because it adds to you TWO deepfreezes and TWO FFO in the begining rotation so you have another pot when DF is off of CD again.
Furthermore, you pop your coldsnap at the begining of a fight for two reasons, DF #3 is off CD faster, and there is a SIGNIFICANTLY higher chance that your trinkets are both up in the first ~12 seconds.
Also not sure if "Because a person needs to do their own research on their class. And needs to look upon.
other top ranking mages and compare themselves." was arrogance or stupidity.
TOP MAGES normally get fed buffs such as innervates, dark pacts, power infusion, the list goes
Don't bash people when you are the one that is wrong, and don't spread misinformation.
All in all, if you base your info off of the top mage on WOL, you sir are in extreme error.
