Hexdrinker does not need any AD to be good
All credit goes to FalconPawwwwnch but this really seems like a solid change to the item.
Hexdrinker is currently a commonly built item by AD champs and builds into maw.
BUt why does Hex Drinker need to have any AD at all?
It would be bough if it gave 40 MR and the passive shield it currently has for something like 900 gold total building out of only a Null-magic mantal.
It would be comparable to Warden's mail as an MR item.
Yes this means zed has to actually counter build to contend with an enemy mage for a little while early to mid game without getting some boosted AD for rushing hexdrinker.
It could then be used to build into Maw and Wit's end which might make Wit's end something for more champs to actually consider getting.
Yes the MR shred is the reason why some champs who like on hit and attack speed will not get wit's end and the lack of it ever showing up outside of a select small group of champs like shyvana, WW or udyr once in a while suggests this item is in a really bad place. Stop trying to save this item for a really small group of champs who have enough magic damage to justify the MR shred.
