[Client] Countless Item Set errors on item info - Needs "Clarity"
This post is about the Item Sets feature on League of Legends Client, particularly when editing those sets or otherwise browsing items outside of a game. This can be found from "Click to view/edit your summoner profile" -> "Item Sets." These errors are showing up every-time for me. Several items are given incorrect, outdated, or simply neglect to include relevant information as other items do. Each item listed has its forum-icon shown, is under a category that matches the problem, and has a place in the picture (added as an attachment below) that show their flaws. Most are errors involving which maps they are "not available on," but also includes missing content or other flaws as described below.
Missing icons:
Black Spear
Any item that is unavailable on Summoner's Rift does not have text saying so:
- Crystal Scar/Yellow-border variants:

- Prospector:

- Other:

Items removed from game, yet still in item Sets:
- Showdown:

- Jungle/Vision items:

Items with incorrect availability (from patch 5.13 or prior):
- Two Luden's Echo, yet the updated version says "not available" on Crystal Scar:

- Needlessly Large Rod hasn't been updated; still "not available" on Crystal Scar and Twisted Treeline:

- Twin Shadows with yellow border and Hextech Sweeper (the legendary item) still showing available on Twisted Treeline

Scrying Orb (trinket),
Farsight Orb (trinket),
Sweeping Lens (trinket), and
Oracle's Lens (trinket) should be "unavailable" Howling Abyss; but only is shown on Warding totem & upgrades.
Missing Trinkets- These simply aren't in the Item lists menu:
Soul Anchor for dominion &
Hextech Sweeper (trinket) for Twisted Treeline
A lot of these problems are old, some dating back to around season 4. These are likely just missed content and outdated information that wasn't properly looked over or changed.
