And Riot wonders why people want to be able to change the recommended items....

Well, to be fair, BFT is almost mandatory on any AP, so do you really need it recommended? :P

All kidding aside, there used to be a way to modify the recommended items.

The following exe may not work though since it's a bit outdated.

There's also another post by Brackhar I believe that explains how to create an ini file that does it.

Now, I don't know if that still works with the new UI, but you can give those a shot.

There are recommended item changers that work with the new store.

I play Ziggs without it, and STILL dominate. It's a broken item, and I'm still waiting for the patch that fits it in as an endgame item as far as build cost. Yes, it makes 90% of AP champs better, which is why it is being reworked. It's really funny when you see the other 10% try to build it.
