See title. Berserk works as an individual button, but as soon as you put it in a macro (which you will likely always e.g. with trinket/tiger’s fury), it won’t work?!
I had the same issue with celestial alignment, till I realised that the talent forces you to use @cursor due to lunar beam. So check if there’s a secondary effect or action needed.
Mine still works though
I use it like this
#showtooltip
/cast [spec:1,@cursor] Celestial Alignment
/cast [spec:2] Berserk
/cast [spec:2]Tiger’s fury
/cast [spec:3] Incarnation: Guardian of Ursoc
/cast [spec:4] Incarnation: Tree of Life
/cast [spec:4,@player]Innervate
/cast Nature’s Vigil
