This could have been avoided by simply making more than mages and baron deal magic damage. If you're tanking a split team that has mostly magic damage but maybe an ADC and bruiser, it's better to build HP and armor with 1 MR item because baron, dragon, towers, all minions, all monsters, and all auto attacks deal physical damage.
Split damage on towers between phys and magic, make caster minions do magic damage, make baron entirely magic damage. They wouldn't have to nerf armor if this were the case.

exactly i wonder if most people realize vayne dose not even build as much damage as other adcs most the time she just builds more as then most to go those w procs
For the love of god, it's the 70 AD steroid that makes her ridiculous and is the principle reason she builds more aspd. The silver bolts, even on tanks is almost never the majority of her damage. You need something stupid like 600 armor and relatively low max HP for it to crest 50%
