The MR steal isn't why anyone picks up wits end anymore, it is just far to expensive for that.
The only reason anyone would ever build it is for the 40% attack speed and the on hit damage. Namely devourer junglers, who use mostly absurd attack speed and on hit effects anyway.
Riot should just remove the MR steal part, while it is neat, it just makes the item far to niche and unused. Lower the gold needed to buy Wits End to 2,000 gold, and the pieces just a recurve and a negaton.
Ideally, making Wits End into a regent for another item would be the best. Perhaps make it so only champions without smite can buy it, to help out on hit laners, so that they don't have to jungle if they want an on-hit build. Think of the path being like a devourer, but for the lane. It would build off of minions and towers, along with champion kills.
would love this.
