This build, as much as I love calling sexy barriers, is more of a niche. Used primarily in high damage fights where support roles are rotating barriers rather than warhorn. This allows you to maintain the major force buff while mitigating damage using the barrier. The alternate morph of barrier that restores health may be necessary in certain situations, but replenishing allows you to regain a lot of your used ultimate and recast barrier in a shorter amount of time. While the barrier is up you are allowed a couple seconds to refresh HoTs in high damage fights such as vHOF HM last boss execute phase.

You DO NOT need perfected saxhleel as a healer, it gives you an extra slot of stamina which can help, but is essentially unnecessary. Non-perfected works just fine.

In fights like vHoF HM where you are rotating barriers and both healers are on group, the other healer may already be using Spell Power Cure, in this case you would put Jorvuld's Guidance on body for SUPER sexy barriers (45 seconds of major force with a full ultimate charge).
