Blizzard will be doing tuning on many trinket and item changes in Shadowlands Season 4. Good news for Strength (and certain Agility) users, Gavel has not received any listed changes!
Below are the changes listed in the Season 4 Patch Notes. In particular its worth noting that the Strength 2-Handed Mace Gavel of the First Arbiter that is also close to, if not, best-in-slot for Agility classes like Guardian Druid/Feral Druid, is not listed.
