The thing that should stand out to to people is that they always wanted it this way. When the talent tree revamp came out on the 2nd they said:
The rate Lava Surge procs now is exactly what they intended from the start but the bug got in the way of it. I’m going to guess that they did not know what was causing Lava Surge to proc like crazy with multiple Flame Shocks until recently when they figured out Searing Flames was the culprit. Notice the terminology they used: “Resolved an Issue”.
The mage community is also way more unified where as both Enhance and Elemental are constantly fighting a war between Storm vs Elementalist or Fire vs Lightining Builds.
