Did they nerf Frost Mage?

• Fixed an issue where Splitting Ice's damage modifier would not apply to Frostbolt, causing both Frostbolts to hit for full damage.
• Fixed an issue where casting a Frostfire Bolt and then switching to Spellslinger Hero Specialization would cause Frostbolt to have the Splitting Ice damage multiplier apply to the main target in addition to the secondary target.
• Fixed an issue where a Splitting Ice Frostbolt had a smaller search radius for its second target than other spells.
• Fixed an issue with Shatter where if two Ice Lances were in the air at the same time, with the first benefitting from Fingers of Frost and the second not, neither would benefit from Fingers of Frost. This could also occur with Thermal Void, which is also fixed.
• Fixed an issue with Crystalline Refraction where interrupting Ray of Frost by casting Ray of Frost could cause it to not generate Fingers of Frost.

Frostfire

• Fixed an issue preventing Frostfire Empowerment's effects: applying ⇒ the second target when Frostfire Bolt hit a second target due to Splitting Ice
• Frostfire Infusion's tooltip has been updated, functionality unchanged.

Spellslinger

• Splinterstorm is now trackable in the Cooldown Manager as a Buff.
• Splinterstorm is no longer removed on start of a raid encounter or Mythic+.
