It’s a bad day for Retribution, as today’s hotfixes bring all the nerfs for the spec.

Retribution

All damage reduced by 3%.

Instrument of Retribution duration reduced to 9 seconds (was 12 seconds).

Fading Light – Blessing of Dusk causes your Holy Power generating abilities to also grant an absorb shield for 3% of damage or healing dealt (was 10%).

Aegis of Protection increases the value of Shield of Vengeance by 10% (was 20%).

Shield of Vengeance duration reduced to 10 seconds (was 15 seconds).

Lightforged Blessing now heals you and your party for 2% of maximum health (was 3%).

Developers’ notes: Retribution Paladins have been overperforming both offensively and defensively, so we’re making some adjustments here to bring them more in line with our intentions. Additionally, we have a hotfix coming at a later date related to Execution Sentence and its unintended interactions with various damage boosts.
