Change Thornmail's stats so it doesn't feel like trash to build.

In it's current state it's basically just a way for melee/tanks to apply grievous wounds. Often times Omen is the best choice against auto attackers, but the Cold Steel passive gets wasted when you buy Omen/Thorn as you'd want both to best counter build heavy auto attackers (reduce damage/attack speed/lifesteal).

Currently all I do is build Bramble as it provides the only thing that matters on thornmail, and then immidately build into omen. I'd rather see the cold steel passive on removed and the gold value budgeted towards HP and CDR or just 1 of the two, you can tune the stats if need be but overall the build would feel much better.
