Spirit bomb question

[Canori-stormrage]

Hey all,

Icy veins says something about Spirit Bomb:

Spirit Bomb is the best choice in this tier. Lesser Soul Fragments are capped at 5, so you want to press Spirit Bomb with 4 or 5 Fragments to get as many global cooldowns as possible over the course of an encounter. This provides the highest amount of DPS for the row for both single target and AoE.

However, a youtube guide says only cast Spirit Bomb when the debuff is about to run out, and cast Soul Cleave otherwise.

Currently, I stack 4/5 fragments, cast Spirit Bomb, stack fragments to 4/5 again and just go with Soul Cleave, only using Spirit bomb for the healing debuff.
If Icy Veins is right, and the best dps comes from just spamming Spirit Bomb every 4/5 fragments, what is the point of using Soul Cleave? If SB has more dps, thus better healing because 10% of better dps is better healing…

Thanks for the help!

When you play SpB you press it always when you have 4-5 soul fragments available. That is your main priority. You press soul cleave only when there is no soul to dump your pain.
Also soul fragments have priority over pain. So do not worry too much about overcaping it.
Soul cleave is used only when you have no souls available to consume with SpB and free global to spend.
SpB provides burst healing and damage which is important. Using it only for the debuff is stupid thing, because the debuff is the least important thing about SpB.
