Talent take rates

There is no single Preservation build. Take the spec talents on the floor list, then choose the rest from the keys you actually run.

The band samples are 5 runs at +10-14, 0 at +15-17 and 0 at +18 and up. That is 5 of the 6 builds recorded. These runs go from +2 to +20, so keys below +10 sit outside every band and the overall column is a different population from the band columns. At these sizes a 60 point swing is safe to act on and a 5 point one is not, so nothing under 20 points is listed below as a trend.

The floor: take these and stop thinking about them

0 talents appear in 95% or more of recorded builds and move by less than 20 points between bands, so the floor is stated as one overall figure rather than a per band one. There is nothing per band to report about a talent that never drops below 95% anywhere.

Those 0 are two different kinds of thing, and the difference matters if you are not on Flameshaper.

The 0 spec and class talents

These are yours regardless of hero tree.

.

If you are on Chronowarden

Skip the 0 hero entries above. You cannot take them. Temporal Barrier is Chronowarden's version of Temporal Anomaly, same mana, same 1.5 second cast, same 15 second cooldown, so that slot on the floor list swaps rather than disappears. Temporal Barrier sits at 50% overall, which is about what you would expect from 6 Chronowarden runs.

Only the 0 talents named above were checked against the hero trees. If you are on Chronowarden, check the rest of the 0 against your own tree before copying the list wholesale.

Talents that come in as keys get harder

Pick these up at +15

Take rate per band, with the band's run count in its header. A band with fewer than five runs shows a count instead of a percentage, because a percentage off four runs implies a precision the sample does not have.

Lifespark is the earliest switch in the whole set. It jumps -40 points between the bottom band and the middle one and then barely moves.

Pick these up at +18, they climb the whole way

Three talents that rise at every step rather than switching on at one key level.

Take Field of Dreams and Fluttering Seedlings together or take neither. Field of Dreams grows one of your Fluttering Seedlings into a new Emerald Blossom, so it does nothing at all without Seedlings. Both hang off Emerald Blossom, which is already one of the most pressed buttons in a ramp window. These two buy you more from a button you press anyway.

Pick these up at +18, they dip in the middle first

The middle band is the low point for all five, and the top band is the high point for all five.

Do not read the middle dip as a reason to drop these at +15. With 0 runs in that band a dip of that size is real, but the reason for it is not in the data. All five are more common at +18 and up than anywhere below. Shape of Flame and Dream Simulacrum are close to universal there.

Talents that drop out

Thinned out by +18

Five talents that survive in the bottom two bands and thin out at the top rather than disappearing.

These five are not one category, whatever the shared shape of the numbers suggests. Trailblazer and Extended Flight are the mobility talents, and both of them are Hover talents. Clobbering Sweep and Terror of the Skies are crowd control: one cuts Tail Swipe's cooldown, the other adds a stun to Deep Breath. Wings of Liberty is neither of those: it is a second charge of Verdant Embrace, which is healing. So whatever is pushing these out of top band builds, it is not one decision about movement. The others survive in a minority of top band builds, so they thin out rather than vanish. Below +15 all five are common enough that keeping them is not a mistake.

Gone, or nearly, by +18

The time themed cluster. Four of the six reach zero in the top band, which is a different thing from thinning out.

If you are pushing above +18, most of this cluster goes entirely and the rest is a minority choice.

Two that do not follow a line

Time Spiral peaks in the middle at not measured, against 20% below and not measured above. Ancient Flame goes 60%, then not measured, then not measured. Take them or leave them.

Other movers

Talents that move at least 20 points across bands and are not covered by a group above. This table is the catch-all: anything that starts moving as more runs land appears here rather than going unmentioned.

Not moved by key level

3 talents are common enough to be near default. Nozdormu's Teachings at 50%, Instinctive Arcana at 83% and Bountiful Bloom at 100%. Take them all unless you want the points elsewhere.

Exhilarating Burst sits at 50% and does not move by key level. It is the one genuine split in the data. Several talents land nearer 50/50 overall, but those split by key band rather than by preference, and you will find them in the tables above.

Below that, Flow State at 17% and Innate Magic at 33% are minority picks.

The rest of the list sits lower still, including Chronowarden itself at 100%, which is the hero tree split again rather than a talent. The key level movers above still carry overall rates in the teens and twenties even where they hit zero in the top band, so do not read a low overall figure as a dead talent without checking its band column.

Every talent below the floor whose rate moves less than 20 points across the bands, sorted by overall take rate. These are real choices that the key level does not appear to make for you.
