A Suggestion For Warmog's armor

After being changed and only functioning after obtaining at least 3,000 health, I've still been getting a good amount of teammates and enemies in my games that decide to buy it before even hitting 2,000, essentially only having a bunch of for a good duration of the match. Is there a way to implement some kind of bold, red tooltip text and/or outline around the item's box to more easily indicate that the regen won't be working unless they have the designated amount of HP?
