I think Randuins needs a little price reduction
Let's face it, even with the outstanding -20% Critical Strike Reduction and attack speed reduction that might have success against ADCs,
remains a very undervalued item with a terrible ~85% gold efficiency (if you count the passives and active).
Even most Bruisers and event Tanks don't build this item because other items such as Gargoyle Stoneplate
and it's amazing passive, Frozen Heart
and it's passive , Dead Man's Plate
and probably even Sunfire Cape
are way over Randuins right now.
The big hit of this item was it's Health reduction that also hit this item against damage that's not critical strike. I think this item deserves a small price reduction (200 to 400 gold less) would really make this item more buyable across most tanks, bruisers and even have a choice for ADCs between Guardian Angel and Randuin's Omen.
