looking over the DPS upgrades for wiz my AA order going live might be Sorcerer's Vengeance (Rank: 36-40) (Level: 120) Focus: Ethereal Skyblaze (Rank: 18-19) (Level: 120) Focus: Ethereal Rimeblast (Rank: 18-19) (Level: 120) Focus: Ethereal Flash (Rank: 18-19) (Level: 120) Focus: Claws (Rank: 18-19) (Level: 120) Focus: Vortexes (Rank: 17-18) (Level: 120) Arcane Fusion (Rank: 8) (Level: 120) Focus: Evoker's Synergy (Rank: 15) (Level: 120) and the focus AA I use will be next PS. Damage over time abilities are currently outperforming nukes in far more scenarios than intended. As a result, the following AAs have been adjusted to compensate: Wizard - Destructive Adept - Increased the percentage damage modifier at all ranks, up to 160% at max rank.
If you can grind for hours with a single group and maintain 100% crit rate then you won't see a big change. Most groups can't do that for casters.
