Blizzard has responded to more Season 3 trinket feedback!
Original Blue Post
This is something we’ll keep an eye on as players get their hands on it. Trinkets with tradeoffs such as cast times, self-damage, or abnormal positioning requirements are intended to feel like a choice and an investment, and the payoff should be worth it both when considering both the numerical DPS contribution and the subjective ease of use.
As in the case of the Al’gethar Puzzle Box and Unholy Death Knights, role-specific modifiers are a tool we are more likely to consider when a trinket is substantially overperforming due to class mechanics as opposed to falling behind due to scaling differences.
One more follow-up to this specifically regarding Augury of the Primal Flame and caster performance after reviewing some additional data: the proc chance has been changed to scale with the player’s haste. This will significantly increase its performance for specializations that prefer haste without much impact to melee specializations that do not. Thank you for helping to highlight this discrepancy!
