No its not a good build, you should not get destructo disk because they reduced the Dots and you should max rapid shot and double bleed and sleep, kaioken isn't very useful for spiritualist.
1) its not build for 55 lvl
2) Get passives from master class they are good (at least 1 lvl)
3) stun shoud be 2 lvl (if u think about pvp).
4) I think u dont need to max both AOE with 4 sec casting. Think about one (in 50 lvl+ u will be use one of this spell). I prefer to use Tri beam ;)
5) u maxed dmg from dot passive, but u just have 2 DoT skil (and one maxed).
