You know, I was just looking into my Buy Back and looked up Astral Guardian on the wiki. Now there's practice that should return; AC-purchasable options to Membership Package sets.
Astral Guardian (AC)
Astral Guardian (Special)
LightCaster (BoL Shop from Upgade)
LightCaster (LTS Shop during Upgrade Promo)
Astral Guardian (Special) comes from the Book of Lore with the wiki mentioning, "This shop is unlocked by purchasing the 5,000 AC Package or 3 Month Membership Package between April 12, 2013 and April 24, 2013."
In that regard, the AC option was sold in a shop in Battleon promoting it, Astral Guardian (Battleon) in this example's regard.
For people that may not be in a position to purchase Upgrade, they should at least have the option to buy the items in said shop(s) for ACs, in this case, Ragnar having a shop for the current promotion of Infernal Naval Commander set.
Edit: A bit late, but the idea considered, I suppose it would have been better set in the Item Set suggestions, but placed in Armor since, the idea was inspired by an Armor.
Edit 2: Another example I've noticed of this being done more than once, ironically enough, was back in the days of OG Lightcaster. Once again, it was both an Upgrade Package, and there was an independent shop to purchase the AC Non-Upgrade Items for ACs.
