+1 Assassin's Blade
When I think paladin, I don't think assassin. I doubt there's space, but it would be a thematic change to ditch paladin.
The plethora of rare weapons does mean +2 Arrow got squeezed out, which I don't care specifically about, but it means there's no rare Enchanter's Munition token, which seems a bad idea. Just kidding, I do care about it specifically. +2 Arrow fits with what else is going on, in particular the emphasis on Bows and the rare Quiver. Oh, and Ranger transmutes kind of want ammo, too.
I really doubt someone is going to get perturbed if one of the +1 1h weapons gets ditched, like the bastard sword.
+1 Claymore
Not a reprint, unlike Claymore, but it uses the reprinted uncommon damage wheel as a model when the reprinted damage wheel doesn't make sense.
+1 Heavy Mace
Reprint with different damage wheel.
600 GP Unpilfered Idol
I don't know about this break from recent history. I'd happily get rid of Withering Runestone to restore the usual GP pattern. But, maybe, that has more to do with lack of interest in any Runestones than in GP being smoothed out over three tokens. I guess it's an interesting experiment to see how much complaining there is about gross imbalances in rare values beyond the other gross imbalances in rare values (resurrection potions versus not resurrection potions, for instance).
Amulet of Vigor
I guess I don't feel strongly enough to argue about the size of the stat bumps. But, I do wish there were more +Con/+Dex tokens a la Bracers of Fast Fitness. While neck may deserve a power bump at rare, recent years are very, very STR happy at lower rarities now.
Boots of Shocking Step
When compared against two UR boots, this seems really good. Should make lots of players below UR level happier.
Dust of Mending
Spell could be capitalized.
Mail of Luck
While obviously not Lucky (except for ... nvm), this is exceedingly confusing to print in the same year as the Lucky set. This should either by Lucky or should be Luckless. Lockless Mail, anyone? Okay, then.
Also, if Nether Fate Armor is any guide, seems like a rare would go to AC +3 and +1 Saves, but it's hard to say if this makes sense. If this armor were to be part of a multirarity set, which I think is interesting, though I can see complaints if the only way to set bonus is to get an UR, AC +3 and +1 Saves at rare seems fine. If not part of a set, seems half an AC under.
