I never vendor or delete gear just because my current spec can’t use it. If it has the right secondary stats for another spec, it goes straight into my bank. That way, if I decide to switch specs later, I already have a gear set waiting instead of complaining that I have to farm everything again.
Planning ahead solves this problem. Deleting potentially useful gear and then blaming the game’s design for having to re-farm it doesn’t.
Getting a full set of myth track gear with three pieces of jewellery that have the correct stats, two crafted items, and two good (But maybe not bis) trinkets is a deterministic certainty with the resources we have available at this point in the tier and it can be done in the span of a single reset.
This is the easiest WoW gearing has ever been and you are genuinely delusional to think otherwise. No rng, no concessions in ilvl or track. Literal deterministic acquisition for enough myth track items to cover every slot.
Lots of people often get hung up on having the ideal secondary stats, when it’s improving your skill that will have vastly more impact. Just switch already and work on your game play while gearing. If you have crests you can make a bunch of crafted gear with ideal stats too.
Were you going to fully pivot to Sin or did you still want access to your Outlaw gear?
Sin uses the Tier Helm and Shoulders for PvP (Outlaw uses Hands and Legs I think). If you have a Conquest Helm and Shoulders you can catalyze them to use for Sin and run 4 piece in the meantime.
The Cloak also catalyzes to Vers-Mastery if you have a Conquest Cloak. And you can recraft any crafted gear from Haste to Mastery.
You’ll still have a fair bit if haste but hopefully as you play and gain conquest you’ll be able to replace gear with better stats. Good luck!
Unless you are pushing for rank 1, your stats probably don’t really matter. Being better at the game will make way more of a difference than your stat allocation.
Just buy gems and ring enchants for the other stat
