I remember seeing builds in pvp arenas utilizing Spirit's Strength, which I thought was a good place to start.

This is what I've been working on, so far it has been a lot of fun. It's not the greatest of builds, I know, but it's different from the Ritualist status quo. It's basically the Ranger barrage bar with a Ritualist twist (lol). It does decent spike damage to balled up groups, and bringing a hero with splinter almost guarantees 100% uptime for Spirit's Strength bonus, they like to spam it on you. Single target dps is pretty low, though.
Grab a 15^50 zealous flatbow, spam volley, have a good time!
Do you guys have any other similar Ritualist builds to curb the spirit spam boredom? I would love to see it and try them out!
