Items that needs to be addressed
League of Legends has a lot of items over the years. Some being under-bought, some being removed, and some just plain not useful. There are several items that comes to mind when I think about that.
Nashor's Tooth ; 
Manamune/Muramana ; 
Zeke's Convergence.
Nashor's Tooth although not overlooked is considered useless on most champions in the game. Sometimes it's not even worth considering on champions that can use this item. Perhaps change the passive to a ramp-up magic damage on-hit that scales with AP.
Manamune and Muramana has been always an overlooked item because of its stats and passive. Considering that its passive is extremely useless for most AD caster champions. Unsure how to change this, but I would like it if this can be more useful on AD caster champions as it is meant for those kinds of champions.
Zeke's Convergence has been a hit or miss for me. On one hand, it seems good on paper. But when put into practice and considering other support-related items, this is honestly not as useful as those such as 
Locket of the Iron Solari or even 
Athene's Unholy Grail.
I would like to know if Riot has any ideas on how to change some of these as they are either under-bought or not as useful as they intended to be or both.
