This has been discussed before. You should not use provoke has your only pulling skill, you should not use it when regeneration skills active or you have an inexperienced group. But it has nice range costs no tp and can be useful for speed runs and grouping mobs together from a distance.
This reminds me of when the game was launched and people where telling WHMS not to use medica 2, regen, or cure 3 because of emnity and now we have a bunch of healers that don't explore all of WHM abilities. Divine seal swift cast medica 2, regen, presence of mind cleric stance, holy holy holy..... click off cleric stance pop shroud of saints= GOD MODE HEALING in df. You can add or subtract shroud at the start of that rotation or end just mp management.
