So this is my personal take on it...
Arms is crit and fury is haste, yes. Probably even more so now than in BFA. Arms has a very narrow burst window with Colossus Smash and the more crits, the merrier in there. Fury only benefits from mastery when enraged, so pulling the bloodthirst CD down as much as possible keeps their dmg up.
That said, no it doesnt really matter. Warrior damage mostly comes from crusader procs and whether I've got 10% or 15% haste or dithering over 2% crit vs 2% mastery is inconsequential compared to whether Im at 0, 1, 2 or more crusaders. If I have double crusader and colossus smash up, you're in trouble regardless of whether Im haste or crit built. I ran a crit fury build in BFA just fine and I cant imagine its changed too terribly much.
From there, I am of the opinion that warriors should stack as much Talasite as reasonable (ie, dont give up a great piece of gear with one socket for a trash piece of gear because it has 2 sockets) for both the "2 crusaders, I win" factor as well as the cascading effect it can have on your healers mana. More health = more flexibility in their GCDs.
Now assuming talasites get the nerf, you have more interesting choices. Id assume they get nerfed to 3 stam (a safe bet, I think) and so now we get to ask, do I want 3 stam or 2/2? both of which have legit arguments.
