Would a MR/Armor Item be interesting to have in this game?
A item like 
But instead of AP it would give MR per monster

they already have MR/Armor item... named Guardian Angel... and Moonflair Spellblade (not in SR though)... and possibly new item Zz'Rot Portal (maybe still stuck in PBE)...
but other item that grants MR/Armor is great too... but granting MR (or Armor... or any defensive stats... except Sion Health) based on unit kills is broken...
More like we need a AD+something item that also gives 2.5 sec of untargetable
