Wits end. Underpowered? To Situational? Or needs a buff/removal?

Wit's ends has remained in the game for a relatively long period of time considering its incredibly low buy percentage almost on par with say Ohmwrecker. Considering in the new season MR runes have been taken away unless you go secondary for resolve tree, Champions who've previously been kept out of their roles have sprung into greater prowess. Teemo (even support), Katarina, Rumble, Sona, Zyra etc. have been finding greater success against this early nerf and for most AD non-tanks in the game Maw has been the staple choice to counter AP heavy compositions since Steraks is now not available for ranged champions to mitigate burst. The AS stat that it offers which certainly makes it appealing to only a select few group of champions, It is one of the few items that gives offensive power matched with respectable defensive stats (Steraks, GA, Zhonyas, Banshees veil, Maw etc.) And is also a very cost effective item for what it can provide. I guess what I'm getting at is I just want some more opinions does this item need to be buffed? removed? or reworked. In a time where the classic flat MR runes have been removed and liandrys/sorc boots has become a go to early rush to abuse this shift on champions that would typically not build it early otherwise so early. Wit's end is the only item that offers both attack speed and magic resistance remains a sleeper still. I Occasionally play champions that benefit from this item against very heavy AP comps and am regularly flamed for buying it regardless of how cheap and efficient it is, I feel as though half the community doesn't recognize it exists. I know its situational and I said that. But it belongs to a small group of items that offer both survivability and offensive power so why is it so ignored. Give me your thoughts guys.
