The item is not for everyone. Its for AD champions

The same way I buy on  or  being bought by  players as it gives mana but yasuo cannot utilize it.

I assume Warrior Crossguard would be bought the same way is being bought

And mostly likely Marksmen wont buy it since it scales with armor and gives them low offensive power. Its specialized in armor increasement
