FOTM Guardian (build setup)

PVT is okay for you to learn with but eventually you will want to gradually replace your gear with berserker’s because in higher level fotm mobs’ health pools get higher and higher and hit hard enough that tanky stats stop helping you.
random staff for empowered is fine
GS is good for pulling the mobs together, I prefer hammer for group wide protection but that is my personal preference.
As for which build, it depends on who you play with. If you have a static group with an ele who is willing to use lightning hammers than a consecration build will do wonders because they can keep blasting your fire fields.
If pugging you probably want to use more shouts instead, something like:

swap WoR to purging flames when you don’t need projectile reflections (water and cliffside fractal)
