Ya, and unfortunately a Precise Arcane actually deals more DPCT and DPF than Aimed Shot, which means from a damage perspective, I believe it’s actually better to use those Precise Shots, which means the vast majority of Dead Eye’s benefits are wasted.
But to be honest, part of that is that Dead Eye is hilariously right now. It’s not providing 60% increased cooldown rate for the duration, it’s providing a 60% reduction in the cooldown time for the duration. In other words, rather than CD / 1.6, it’s CD * 0.4.
That means each Dead Eye, rather than restoring a bonus 15% of an Aimed Shot charge per Kill Shot (ie. 4.8s of CD over 3s), instead restores 37.5% of one (7.5s of CD over 3s). And the thing is, that gets larger the more haste you have, because the duration is fixed. It’s actually just straight up multiplied by your haste, turns out. At 33.3% haste, for example, it instead restores 50% of an Aimed Shot chart (37.5% * 1.333)*.
And the weird part is, I’m pretty sure this is intended, even though it’s clearly not what the wording suggests, because they recently changed it. It used to say it gave “50% faster recharge”, but actually cut the CD by 66.7%. Now it says “60% faster recharge” and actually cuts the CD by 60%.
A proper wording for that would be “reduces the recharge time of Aimed Shot by 60% for 3s”. “Cools down 60% faster” says to me it should be acting like I gained a 60% haste buff, for the purposes of the cooldown. ie. the cooldown progresses through it’s “cast bar” at a 60% higher rate of speed, so the CD time becomes CD / 1.6.
However, this really highlights that MM is exceptionally brittle about it’s rotation. Giving us more AiS charges doesn’t necessarily increase our DPS substantially, because our focus balance is so easily thrown out of whack.
Part of this is because AiS requires a rather exceptional commitment per charge. You have the 2.5s cast itself, 1.5 Arcane Shots following it to consume the Precise charges, and then 2.2 Steady Shot costs to balance out the 65 focus consumed (also accounting for passive regen over the duration of everything). Net is that, per Aimed Shot charge, we have a mandatory 8.6s of casting to handle everything involved. Even if we drop RF and unbonused Arcane Shot entirely from the rotation (though iirc, RF is now higher DPCT than Aimed Shot), that means we are still limited to just a smidge shy of 7 full Aimed Shot combos per minute, and we get 5 innately by cooldown.
I’m more convinced than ever that Precise Shots needs to be taken out back and murdered. That would at least solve the capping issue in most cases, since the mandatory commitment time for AiS would only be the cast itself (2.5s) and the 1.2 Steady Shots needed to make up the focus, for a total of 4.6s. That gives us 13 combos per minute (though less if we’re still including RF and Kill Shot).
