Raid drop from Nek'zali the Soulcoiler - the best in-raid match for a Haste profile, and the Catalyst now carries those secondaries onto the tier piece intact. Crit / Haste - LFR 279 - Normal 292 - Heroic 305 - Mythic 318
From the Season 2 M+ pool (Kings' Rest), so you can farm it on your own schedule instead of waiting on a boss - a real advantage when the donor's stats already suit Haste. Haste / Vers - M+ 292 - 311 from the dungeon, 318 from the vault
The no-charge fallback. Redeem the token, wear the tier piece as it drops, and keep your charges for a slot where the donor actually beats it. LFR 285 - Normal 298 - Heroic 311 - Mythic 324

The live guide's answer for this slot is the set piece itself - either it drops straight off the boss or its stock spread already sits close enough to Haste that no donor in the field is worth a charge. Redeem the token, spend the charge somewhere it earns more. LFR 282 - Normal 295 - Heroic 308 - Mythic 321
From the Season 2 M+ pool (Temple of Sethraliss), so you can farm it on your own schedule instead of waiting on a boss - a real advantage when the donor's stats already suit Haste. Crit / Haste - M+ 292 - 311 from the dungeon, 318 from the vault
The raid drops no plate shoulders, so the Mythic+ pool and the Lair are the entire donor field for this slot. Confirmed against the vetted Season 2 loot database.

Raid drop from The Coiled Altar - the best in-raid match for a Haste profile, and the Catalyst now carries those secondaries onto the tier piece intact. On Mythic this is a boss 7-8 drop at 344 (above the cap), so catalyzing it is a genuinely expensive flex. Haste / Mastery - LFR 289 - Normal 302 - Heroic 315 - Mythic 344 (above the cap)

Mastery cantrip legs that stay a Mastery cantrip after conversion, at 344 on Mythic Ula'tek, above the crest cap - about ten item levels clear of anything else plate can feed this slot. Mastery (dominant) + cantrip - LFR 289 - Normal 302 - Heroic 315 - Mythic 344 (above the cap)
Raid drop from Entombed Sentinels - the best in-raid match for a Haste profile, and the Catalyst now carries those secondaries onto the tier piece intact. Haste / Mastery - LFR 282 - Normal 295 - Heroic 308 - Mythic 321
The no-charge fallback. Redeem the token, wear the tier piece as it drops, and keep your charges for a slot where the donor actually beats it. LFR 285 - Normal 298 - Heroic 311 - Mythic 324
hot take
You are a wall with a Mastery cantrip stapled to your legs - feed the Chausses and never look at the Relic again.
