I just hope Riot finds a way to make Executioner's Calling a useful item. I've literally only ever seen it built twice, and both times it was by me against an Aatrox before I realized that Grievous Wounds doesn't apply to him during his auto-revive.
Hurricane's another for me too probably, it's only useful on maybe Teemo and Twitch and even then you're better off with pure AD/AP with the stats that it gives. I wouldn't be against a rework, but if it loses the passive, then it's not really Hurricane anymore.
Sight stone: While its a nice item I think it just encourages the ward slave support mentality.
QSS: It's there to counter champs with hard CC like a suppress. It's not the best item but I feel it shouldn't be in the game still. If you want to counter a champ with a suppress then you should bring a champ with a stun/silence/etc. to stop the suppress. Not be able to save the CC to use against someone else and have the suppress be nullified with an item.
