So after checking some logs trying to see how to reduce the damage I take on a mythic raid boss, I saw that Tooth and Claw doesn’t reduce magical damage taken but only reduce physical damage only!
The tooltip of the talent says: (Empowered Maul deals 40% increased damage, costs 100% less rage, and reduces the target’s damage to you by 15% for 6 sec) which should include all type of damage and not physical only which is how the old Tooth and Claw worked.
Also I’ve reached guardian druid discord and with them after checking some logs we found that out, so its not only me :S
Blizzard please fix this!!
