First, I'm sorry if this have already been brought up. Havn't seen anything about it.
Will the new legendary meta gem actually be that much better then the normal meta gem? The crit rating on it will be equally as good as the int on the on the normal meta gem (atleast according to askmrrobot's fire mage stat values). If that is true, then it means that you chose between a 30% haste proc for 10sec vs 3% increased crit damage.
The proc chance of the gem is as following:
Proc chance for fire: 1.18*0.302~0.36.Sinister Primal Diamond – 1.18 base RealPPM on damage/absorb of harmful or periodic spell. No ICD.
- That base proc rate is multiplied by an additional coefficient:
0.302 Fire Mage
1.387 Frost Mage
1.000 Anyone Else
Correct me if I'm wrong, but this means that the gem will proc (for a fire mage) about every 3 minutes (since its using RPPM). If that is correct, you basically gain 30% haste for 10 secounds every 3 minutes. I'm not 100% sure of how to do the math to calculate how much haste rating this would give assuming it proc's every 3 minutes. Someone please help me with this.
Either way, to me it feels like a 10sec haste buff that you cant pop yourself (i.e. it might proc when you're running/not have any CD's up etc) is not better then the 3% crit damage. Crit damage = combustion damage = fire mage's major damage. There's a lot of movement in this tier so the chances that you will proc the gem whilst not standing still nuking is fairly big.
What do you guys think? Someone have any theorycrafting proving wich gem will be the best? Unless it turns out to be a big DPS increase I will probably stick with the normal meta gem since I don't think taking the risk of being forced to move when the gem procs is worth it.
