Evoker lacks a powerful raid buff, with
Benedizione del Bronzo being largely forgettable, meaning the class does not have a guaranteed raid spot. It competes with Augmentation, which brings far more raid utility for comparable or better damage in coordinated groups, though in less coordanted groups it can be nice to not rely on others for your damage.
Maestria: Ammazzagiganti is interesting, though damage to high health targets is often much less valuable than damage to low health targets, unless Fyrakk dies at 45% like Sylvanas did! This may make DPS sims and statistics a bit misleading, as if an Evoker’s total DPS is 110% of another spec’s, but the Evoker is doing most of their damage in phase 1and is doing tank damage in P3, that would make it far less valuable for most end bosses where damage ends up being irrelevant in P1 and hyper-relevant in P3. The good news for Devastation Evokers is that the value of Mastery has been reduced and power has been moved into the rest of the kit this patch, which reduces the size of this effect.
Devestation is also good but not great defensively, with a few strong buttons like
Fiammata Curativa and
Scaglie d'Ossidiana but without an immunity or substantial ability to keep themselves healthy through sustained rot damage.
