AD Malphite or AP Malphite?

Malphite typically goes tank or AP; IIRC he doesn't have any AD ratios, though I suppose you can try to do something like AS/AD Malphite and just smack the crap out of stuff with your W, lol. I don't think it's optimal though

Tank/Armor. His E scales with armor, so you build a decent amount of armor early (don't build too much, it gets pointless late game build more health/MR late). Tanks are really strong right now, and they do decent damage. You could do AP Malphite mid, but I rarely see that and I don't know if it works.

where's the "tanky with iceborne" option.
