So I'm looking at the top build for WDs this season. I've been mostly playing solo so far but I'm thinking about stepping into trying some group play. I haven't done it a lot and I can just imagine how when I join a group for some GR pushing, they'll be expecting me to spec into the trash killer version of the spirit barrage build.
So the two builds are really similar. The biggest one being that in the "solo GR" version of the build, you would use Piranhas and Big Bad Voodoo where in the "group trash killer" version of the build you would be using Zombie Dogs and Sacrifice for the 20% damage buff that Sacrifice gives with the Provoke The Pack rune. So i'm looking at the two builds and comparing, and I can't help but wonder... Big Bad Voodoo has a rune that increases damage of allies by 15% plus the 15% increased attack speed, and Piranhado causes affected mobs to take 15% increased damage. For _everyone_ in the group. Sacrifice gives 20% increased damage for 5 seconds for _just you_, and also involves a whole extra rotation to have to manage with blowing up the Zombie Dogs to keep the buff up while also making sure to reset Zombie Dogs from Grave Injustice.
How is the latter better for trash killing? One increases damage/attack speed of whole group by 15% + increases damage taken by at least some mobs by 15% for the whole group, while the other increases just your damage for 20%, and the latter is supposedly the top choice for GR pushing. It doesn't make sense to me. Even assuming two support roles in the group, there's still two DPS. So it's 15% attack speed/15% damage for 2 DPS vs. just 20% damage for 1 DPS. It doesn't seem logical to me.
