Epic RE suggestions

Anerythris

Rework older legendary REs into epics and adjust scaling. Examples:

By Fire be Purged - changed to Epic.
Eldritch Knight - changed to Epic, 1 second internal cooldown.
Overheating - changed to Epic, remove weapon damage scaling and implement proper attack power/spellpower scaling.
Holy Supernova - changed to Epic.
Benevolent Crusader - changed to Epic, remove the line "that does not overheal". Make it work with Atonement and Holy Radiance, but stacks can only be gained on a 1 second internal cooldown.
Battlemage - changed to Epic.
Plague Bearer - changed to Epic. Rework to let Maul apply Rabies, which deals nature damage over time and increases the damage of consecutive Mauls by 5%.
Zany Zealot/Eccentric Elementalist/Crazy Cultist etc: standardized to one Epic RE - Wild Magic: Every 10 seconds, your next damaging spell with a cast time launches a copy of itself, for 50% of the damage of the original spell. This damage cannot critically strike or proc effects. If the spell is channeled or a damage over time effect, this RE instead applies Chaotic Magic, a debuff that deals chromatic damage (highest modifier) over 5 seconds and increases the damage of your spells by 3%.
Spell Slinger/Harbinger of Flame/Deathbringer etc: standardized to one Epic RE - Archmage: Every 10 seconds, your next damaging spell with a cast time triggers the Clearcasting effect and afflicts your target with Elemental Echo: a debuff that deals 10% of the damage of your original spell over 5 seconds. This damage can critically strike and scales with your highest spell critical chance modifiers.
Soul Bender: changed to Epic. All direct shadow damage spell casts now accumulate Soul Energy, up to 5 (1 second internal cooldown). Using Shadowburn with 5 stacks of Soul Energy guarantees a critical strike and increases your shadow damage dealt by 5% for 10 seconds.
Ice Barrage: changed to Epic, does not work with Frostbolts made instant by Maelstrom Weapon and decreases frost damage done to players by 15% while equipped.
Shadow Visions: changed to Epic. Soul Fragments stack to 6, for 1% haste. Reaching 6 stacks causes your next Mind Blast to give you Shadow Visions, a buff that increases your Shadow damage dealt by 3% for 8 seconds.
Mending Tide: changed to Epic. Your Riptides are no longer consumed by Chain Heal, but increases the cooldown of Riptide to 8 seconds.
Wild Felfire: changed to Epic. Spell haste stacks changed to a max of 5. Increases Chaos Bolt's critical strike by 5%, no longer dispels.
Divine Purpose: changed to Epic.
Warcry: changed to Epic. Cooldown lowered to 1 minute.
Whispers of the Old Gods: changed to Epic. Tentacles removed altogether, the buff now triggers from Shadow Word: Pain's periodic critical strikes.
Blessing of the Divines: changed to Epic. The effects now scale with holy or nature modifiers and with your healing power. Each effect now has a separate 5 second internal cooldown, but the chance to proc them is increased to 15% per heal, doubled on critical strikes.
Overloaded Froststorm: changed to Epic. Number of stacks changed to maximum 5, with a 1.5 second internal cooldown between gaining stacks. The Overloaded Froststorm effect is now a single target DoT that lasts 8 seconds, scaling with the highest of Nature or Frost modifiers and increasing your spell haste by 5% for 8 seconds.
Astral Tempest: changed to Epic. Number of stacks changed to maximum 5, with a 1.5 second internal cooldown between gaining stacks. The Astral Tempest is now a single target DoT that lasts 8 seconds, scaling with the highest of Arcane or Nature modifiers and increasing your spell damage by 5% for 8 seconds.
Battle Fervor: changed to Epic. Stance requirement removed.
