This part.
Critical Mass - nerf reverted. It's back to 30%.
Pyroblast - direct damage reduced 10%.
Critical Mass was nerfed to 1.2 again previously. (few days after 5.1 hit, it was nerfed to 1.2, but slightly buffed to 1.3 again after that.)
But they revised this CM 1.2 nerf again in 5.2 PTR.
But then they decided this change will punish people with low ilvl geared people.
So they reverted CM and simply nerfed the spell damage, which I think is good.
Because I think if they are going to nerf fire, they should nerf the spell damage and not the crit multiplier.
It just ruins the fun for fire if people don't have the best gear available.(lack of crits means you'll be spamming fireball majority of time)
