Patch 7.3 Elemental Shaman changes raise Mastery cap, buff Earthquake

Next PTR will have a small set of Elemental changes meant to focus on a couple specific problems.

Mastery capping
• Elemental Overload does 85% of base damage (from 75%) and proc rate reduced 17%
• Totem Mastery-Storm Totem bonus 5% (from 10%)
• Elemental Blast gives 2000 stats at level 110 (from 2400)
• All damage abilities increased 3%

Some of the power of mastery is shifted from proc rate into damage. The nerfs to Totem Mastery and Elemental Blast don’t require talent rebalancing, since they are minor and those are talents are already generally favored. The slight total DPS loss from those changes is counteracted in the baseline spec. With both talents, the mastery cap (with all these changes) would increase from 10400 rating to 15067.

Chain Lightning dominating Earthquake
Chain Lightning is so strong that Earthquake is often not attractive to cast. There are also secondary issues such as the importance of Lightning Rod procs and resource overflow in AoE.

• Chain Lightning damage reduced 12% and generates 4 Maelstrom (from 6)
• Earthquake damage increased 29%
• Earth Shock damage increased 13%

Damage is shifted from Chain Lightning into Earthquake, and Earthquake is further increased to account for generating less Maelstrom (which helps the overflow issues, including on Static Overload procs). The Earth Shock buff helps stave off the potential for Earthquake to get too close to it again, and a buff to Earth Shock was pretty reasonable generally.

Again, the goal is to address these issues in a relatively contained way. 7.3 is generally light on class changes, but we wanted to try to get at these known problems. As always, open to feedback on any complications that these look like they might introduce.

Thanks. To the various comments here and above:

–If Elemental Blast is actually behind after the small nerf, it should be relatively easy to correct by buffing its own damage. That said, the current set bonus pushes Primal Elementalist (and that sort of thing is generally acceptable for a tier), which means it’s unsurprising if it’s slightly ahead on its row for right now.

–We agree Earthquake should be more of a “finisher” out of the two, and this set of changes is trying to go in that direction. It should at least be used consistently in its intended role. It sounds a little odd that changing one spell’s damage 45% relative to the other (plus the Maelstrom change) doesn’t at all change the number of targets at which you’d use Earthquake, but we’re happy to keep looking at any more detailed discussion of why that would be the case.

–The Maelstrom change would be a pacing change, but I think there are some advantages if we keep it and instead put value into buffing Earthquake (further than this if needed). It helps the above discussion of Earthquake actually being worth enough to stand out. The current version where, on average, each Chain Lightning pays for more than one Earthquake is a pretty weird builder/spender relationship–and is part of the answer to your question of why Earthquake isn’t stronger. Also, Maelstrom overflow is a significant issue currently. In your example of Static Overload, it currently overflows in literally every case (on 5 targets). Pulling back on that and giving Earthquake much higher value cuts down on resource waste while making it more valuable when you spend it.

If the main problem is that the Earthquake buff here isn’t enough to accomplish the goals as described, that’s something we can review further (and of course welcome any further input on that question).
