Elementally Legion: Stats
August 3, 2016 14 Comments
As per usual, a common question is about the stat priority for Elemental and responses are either surprised or disappointed when the answer is “Crit”. More accurately, it’s as follows:
Int >> Crit > Haste ~= Versatility > Mastery
Critical Strike Rating has 2 things going for it: Elemental Focus and Elemental Fury. This means that a critical strike gets at least 25% more damage than a “normal” critical strike and the next two spells get a 10% damage bonus. There’s also a straight damage bonus effect on Ascendance should you take it.
Even though Crit had (almost) zero effect on Lava Burst it was still third in value during Warlords, falling just behind Haste, and there will be some interaction if the cast preceding Lava Burst is a crit.
Haste is a decent go to for Elemental, and has been for many expansions, but the problem for Legion is that as you add casts into your rotation it also reduces the effective uptime of Elemental Focus. This is because it increases the count of your non-autocrit spells, reducing the average bonus Focus gives, which is a negative feedback loop.
eg: 40 spells per minute, 20% crit rate, 10 Lava Bursts = (10 + 0.2 * (40-10)) * 2 / 40 = 80% effectiveness or 8% overall gain
50 spells per minute, 20% crit rate, 10 Lava Burst = (10 + 0.2 * (50-10)) * 2 / 50 = 72% effectiveness or 7.2% overall gain
This is ignoring refreshes where one charge isn’t used (ie: 2 crits in a row) but you can see how the effectiveness of the bonus decreases as more spells are added.
Back in Mists of Pandaria Lightning Bolt & Lava Burst were larger contributors to damage but this has reduced a bit in Legion with the addition of more non-Overload based spells or bonuses/effects that don’t interact with the Overload chance like Power of the Maelstrom. Resource generation is also a bit lower, as in MoP an overload gave 1 extra LS charge out of 6 (or 16.67% of total resources) vs the 6-8 Maelstrom in Legion (6-8%).
Most of the problem is that the stat increases resource generation and thus affects shocks, but that’s slightly incorrect as the more Maelstrom generated means less time spend casting Overload capable spells, or one of those “negative feedback loops” that causes problems for Haste.
Surprisingly, Versatility is about as good as Haste at the moment. It shouldn’t really be a surprise if we consider the negative effects for Haste & Mastery, plus it affects all spells.
