Mana potions are no longer part of the game but they are still visually there in game shop (both blue and red side). There can be many such little things, mana potions are just an example. See the screenshot given in link
TheCeeJay2 votesPhilosopher's Stone, Heart of Gold, Emblem of Valor and old Aegis of the Legion can also be found throughout the map but were all removed or remodeled long before Summoner's Rift got the update. The mana potions are fine and you're nitpicking.
Aryan Tiger1 votesIts not that something I want urgently or want it at all, just a suggestion, wonder why you use the word "nitpicking"
Junsui Aoi1 votesI personally think its cool that they pay tribute to some of the old items. ^_^
Aryan Tiger4 votesyeah maybe "sold" tag on mana potions would look nicer :D or something like that
Junsui Aoi1 votesNow that would be a cool little addition :D
