+// Predatory Strikes (16972 / 16974 / 16975) for Paragon: re-implements the
+// Cataclysm-era proc behavior of the talent so a Paragon's damaging
+// finishers (Eviscerate / Envenom / Ferocious Bite / Rip / Rupture) can
+// roll Predator's Swiftness (69369) -- the same buff that real druids
+// get from the Cata redesign of this talent. Combined with the
+// Spell::prepare interception in core (Spell.cpp), 69369 makes the
+// Paragon's NEXT Nature-school spell with a base cast time below 10s
+// instant cast: Chain Lightning, Lightning Bolt, Healing Touch, Wrath,
+// Nourish, etc. -- not just the Druid-family Nature subset that the
+// stock SPELLMOD_CASTING_TIME mask on 69369 covers.
+//
+// Filter logic:
+//   - Source spell must consume combo points (NeedsComboPoints() — gates
+//     out non-finisher combo-point builders).
+//   - "Damaging finisher": SPELL_ATTR1_FINISHING_MOVE_DAMAGE (Eviscerate,
+//     Envenom, Ferocious Bite, ...) OR a SPELL_ATTR1_FINISHING_MOVE_DURATION
+//     finisher that applies periodic damage (Rip, Rupture). Duration
+//     finishers that only heal (Recuperate) or only buff / CC / armor shred
+//     (Slice and Dice, Savage Roar, Kidney Shot, Maim, Expose Armor) are
+//     rejected.
+//
+// Chance per combo point matches the Cataclysm tuning that the user's
+// client tooltip text reflects: rank 1 = 3% per CP, rank 2 = 5% per CP,
+// rank 3 = 7% per CP. At 5 CP that is 15% / 25% / 35%, capped at 100%.
+//
+// Combo-point read happens during PROC_SPELL_PHASE_CAST, which fires in
+// Spell::cast → Spell::ProcReflectProcs / Unit::ProcDamageAndSpellFor
+// BEFORE Spell::_handle_finish_phase clears the player's combo points
+// (see Spell.cpp:_handle_finish_phase clearing combo points). So
+// player->GetComboPoints() inside HandleProc returns the pre-clear value.
