User blog comment:Deshiba/Wit's End - rework/@comment-26815373-20160224211739

Having your hypothetical Wit's End grant such a high MR boost, on top of granting the magic damage shield equivalent of Bloodthirster is prob a bit too strong. Also, I think there is something to be said about the use of named item effects. If we look at all the varieties of Spellblade, they all read pretty much the same. But this change of yours gives the Lifeline name to an effect totally different from the Hexdrinker or Maw of Mal's Lifeline.

I think Riot could have Null-Magic Mantle build into more items and that that would help with the build path. Also, having Wit's End's build path require two AS items and an MR item that have to sit in you inventory isn't ideal. Maybe incorporating Hexdrinker into the build path makes it easier, but it opens a different can of worms and I'm not sure it really fixes anything.

I think the real issue with Wit's End is that people really want to use Wit's End with her cousin item Nashor's Tooth, but the two items don't synergize all that well. I think a champion who could make use of both as core items would go a long way toward making Wit's End a more useful / popular item.
