LW items are currently too good at countering bonus armor...

And it is way to easy to get a LW and sit on it for a while and still get 66.6% of the power of the items it builds into. And yes for an effective 425 gold you can easily negate the cost of 600 armor from a Frozen heart.

Math for those who question:

Here it is for LW 30% of 100 armor on frozen heart is 30 cost of one armor based on cloth armor = 20 30*20= 600 effective gold worth of armor ignored from a frozen heart.

Here it is for Lord Dominik's Regards 45% bonus armor pen cost an effective 637.5 and counters 45 armor of a frozen heart which is an effective 900 gold worth of armor stats from this 637.5 cost passive. This is not counting the extra 15% damage for having 500 more total health.

IN turn items like Omen and Frozen heart are overall really weak in the current game and way to easy to effectively counter with an item that is actually cheaper then them.

So long as building pure tank items is this easy to counter bruiser builds will be staying the meta for champs like Graves and akali.
