I think it would be a better idea to make the aftermath effects on the relic weapons a static stat on the weapon and change the WS's to "Damage varies with TP". Mythic and Empyrean already have their own individual stat boosts, while all relic gets is normal ilvl stats and the OTD full-time, which is nice don't get me wrong.
I think this would make some relic weapons more desirable and give some nice niche stats to jobs.
Final Heaven(Spharai): +10 Subtle Blow
Mercy Stroke(Mandau): +5% Critical Hit Rate
Knights of Round(Excalibur): +10 HP/tick Regen
Scourge(Ragnarok): +5% Critical Hit Rate
Onslaught(Guttler): +10% Attack
Metatron Torment(Bravura): -20% Damage Taken
Catastrophe(Apocalypse): +10% Haste
Geirskogul(Gungnir): Shock Spikes
Blade:Metsu(Kikoku): +10 Subtle Blow
Tachi:Kaiten(Amanomurakumo) +7 Store TP
Randgrith(Mjollnir): +20 Accuracy
Gate of Tartarus(Claustrum): +8 MP/tick
Coronach(Annihilator): -20 Enmity
Namas Arrow(Yoichinoyumi): +20 Accuracy
Now, some of these like Knights of Round and Claustrum may have been pretty over-powered to have full-time back at 75, but at item level standards they are really not that bad. Claustrum would actually have a use as an idle piece for BLM/SMN. +10 HP full-time I doubt would be broken at all for PLD in end game. -20% Damage Taken full-time for WAR, at first does seem pretty potent, but honestly, most if not all DD's carry DT sets for endgame anyway, all it would do is make it easier for WAR to cap DT w/o sacrificing as much damage as before. A nice situational niche to have on occasion.
If you changed all these WS's to "Damage varies with TP" I think a lot of them would still have use in the normal scheme of things, even without an Aftermath.
If anyone has any feedback on this idea, please let me know.
