MR items
This has been something that has been annoying for a long time, but I feel like I nee to say this. The amount of MR given by the tank items is kinda ridiculous. Abyssal Mask and Zz'Rot Portal builds out of a Negatron Cloak (40 MR) and gives you 55 MR, Adaptive Helm is built out of a Spectre's Cowl (25 MR) and a Null-Magic Mantle (25 MR) and gives 55 MR, Spirit Visage is built out of a Spectre's Cowl and gives 55 MR. Three different build paths, yet they all end with 55 MR. But, Banshee's Veil, now an AP item, is built solely out of a Null-Magic Mantle, but it gives you 60 MR. It has a better passive than the others because there are even fewer cases where Banshee's passive isn't useful. With the buff to AP items coming, I think you should look at the MR items and shift the MR of the items around a bit, but that's just what I think. For comparison, Maw of Malmortius gives 45 total MR from Hexdrinker which gives 35 MR.
