Okay, I asked around for confirmation on my initial reaction. MoM is not a tank weapon. Its usually a Brusier/AD caster item, and I occasionally use it on Trynd/Pantheon. I'll give on Frozen Mallet, but noone is buying FM for that 20 AD. They're buying it for the health and reliable slow on AA. Again, most often used by AD scaling champions who are, traditionally, Brusiers.

Additionally, there are relatively few AD items that feature resistances of any kind (Atma's is the most prominant), where as there are multiple AP items which feature resistances. (Iceborn Gauntlet, Abyssal), as well as items that feature health and fairly large AP values (Rylai's). I could counter the example of MoM with Zhonya's, but neither of those items have any business being on a tank.

You'll also notice that neither Rammus nor Thresh have any actives that scale off AD. They are still pure Tanks and still focus mainly on building tanky and relying on abilities to make their presence felt in combat. Additionally, Thresh's passive scales off more than just AD, it also scales off the number of souls he's collected, which is what people will actually be worried about rather than putting AD items on him.

As for Rammus, with 400 armor, he'd be returning 40 extra damage on his curl, and dealing an extra 100 damage on his auto attack. That honestly wouldn't make that huge a difference in a fight, as he'd still be about using his abilities to disrupt and CC targets. Rammus' big source of damage is his R, which deals a maximum of 1560 + 240% AP in magic damage to everyone within 300. That AD off armor matters far more with jungling over late game damage.

When I said 'reducing his scaling', I was referring to when transitioning from AD to AP on his Q. Frankly, you can leave the scaling for his Q if you keep him AD, but the fact remains that every pure tank, I.E. champions in LoL with the 'Tank' tag, scales off ability power because there are more items that they can benefit from which have AP over AD.

If you're dead set on keeping AD on his abilities, then you might consider throwing AD & AP scaling on both his Q & W. Still, any AD scaling points people toward Brusier rather than Tank.
