Spirit weapons can work in wvw, it just depends on the context. For solo roaming and small group they are viable, they’re actually one of our best 1v1 builds believe it or not. However, when it comes to larger scale fights, they are next to useless because they evaporate in seconds.
Couple of small tips when running SW:
Always take the hammer. It’s by far the best spirit, it has the ability to do insane damage (+5k crits), and has CCs also.
Have a scepter. Since SW builds aren’t known for having great sustain, so it helps to have a range weapon to keep out of melee combat as much as possible, let the spirits do the work.
SW benefit from buffs, so this can open up a number of options. You can go AH and still reap the benefits, furthermore SW have their own stats, and don’t scale with your stats. So this can allow you to go tankier, and let the SW do most of the work, while you just buff them.
