Okay, so, I think I've got a way to make Wit's an attractive buy

Simply put, it needs to be able to hold its own against to secure a position in a Diver's inventory. The MR shred isn't super useful on a wide selection of Divers and the flat magic damage OnHit is more befitting of ~1.5K component item. Part of the problem with Wit's in its Live version is that most of the OnHit items that are attractive to Divers deal physical damage, which makes the MR shred even less desirable than it was when OnHit items basically all did magic damage. So how about we try to make that comparison with BoRK a bit more direct, shall we?

= Grants 30 MR/Ar, 60% attack speed, 10% CDR, and- UNIQUE passive: Your basic attacks deal 4% of the target's max HP as magic damage OnHit. UNIQUE passive: Your basic attacks steal (2 + [1/3 Levels]) resistance, stacking up to five times.

So what have we got here? A really expensive item, for one. That's 3200 gold, not counting the combine cost. So we're probably looking at an item about on par with Trinity Force or Rageblade in terms of price. I could imagine it even falling into the price range of the old Madred's Bloodrazor. Practically speaking, this thing would be for laying the smackdown on high HP, low resistance targets. It would make the user tanky while augmenting the user's damage output. It would pair nicely with both Titanic and BoRK, giving Divers a choice of a sustain OnHit item, a resistance OnHit item, and an HP OnHit item.

So! The only question that matters. Would you buy it on Irelia?
