Mundo AP Ratio Suggestion

Mundo's obviously a tank rather than a mage because he has terrible scalings and good base damage for early-mid game. However, it's frustrating having no offensive options at all other than crit. and mpen. Literally his only ratio is 10% AP so even if you want to go a goofy AP Mundo, you just can't do much for his damage. This is very strange to me since there are many other tanks like Nunu, Malphite, Rammus, etc. which do have quite good damage scalings. That doesn't mean building lots of damage on them is optimal but at least you have those build options.

In conclusion, I'd like if Mundo had some AP ratio on his Q or a better W ratio at least. They're buffing Nocturne and Yi's AP ratios and I was just reminded how sad Mundo is. He falls off so hard late game because he has no hard CC, runs into perma Grievous Wounds from Morello/Executiner and his damage is pretty much negated by LS on a 6 item ADC. With all that, it would be fun to at least have some ratios to toy with.
