52.5 MR = 34% magic damage reduction. Or only 23.9% reduction vs Katarina due to void staff.
His ult would bring him to about 100 or so. Which would be 50% or 37~% against Katarina.
100.6 AR = 50% physical damage reduction. Or only 37.6% vs Ashe, plus whatever 12% + 18% dodge would be. (it's not 30% by the way, I don't remember how to calculate dodge rate)
That's not a lot. Especially when he only has 3052 HP.
(Note: None of the above stats consider runes/masteries as I have no information on that.)
Looking at the other team's item builds, they would tear him apart, especially due to Karthus's wall's AR/MR debuff, Ashe's stun, Teemo's blind, Lux's bind, etc. Plus 2 potential exhausts, which reduce damage and if they have the mastery, also reduces even more AR/MR.
Then you look at Singed. Not a single piece of equipment to protect against magic damage. He also seemed to be building a critical damage item. Irelia should've built aegis over guardian. Better MR (cost-wise) and gives her team moderate AR/MR.
The one thing I'm curious about...
Why did you have two warmogs armors, and an even better question, why not one of them get a bloodrazor because of that?
