Here is proof that the synergy is not working as intended:

This test was done with no Item Sets and equipment, no non-Werewolf passives, and no Champion Points equipped.
According to the U50 Launch Known Issues List, the synergy is working as intended:

However, the tooltip of Ferocious Roar says there should be a 6% Damage Done buff for you and your allies:

The wording implies that casting the ability immediately gives you Major Courage for 20 seconds, which is true, and then the synergy provides Minor Force (which is true) as well as +6% Damage Done. According to the test I've done above,
this +6% Damage Done buff is not being given to people who use the synergy.
ZOS, please fix this. Werewolf won't be desirable in group compositions if it doesn't offer anything unique to groups, like this unique damage buff.
