Because if you follow my build you'll have enough armor/magic res. The more armor/magic res you have the less each additional point benefits you, but health will always benefit at an even rate. With the build I posted you'll have all you need. You might want to go with a sunfire instead of randuin, but I like that I can rush heart of gold and get some gold by doing that.
As I understood it each armor point gives you 1 % extra EHP regardless of current total armor.
If you have 2000 hp:
100 armor will give you 2000 + 1,0 * 2000 = 4000 EHP against physical damage.
200 armor will give you 2000 + 2,0* 2000 = 6000 EHP.
So you get extra 2000 ehp per 100 armor regardless of how much armor you have (til the cap ofc).
Instead if you buy
1000 hp and 100 armor you will have 2000 + 1000 + (2000+1000)*1,0 = 6000 ehp.
But 1000 hp is more expensive than 100 armor, so it seems stacking could be cost efficient if you face a pure physical team (or pure magic damage team). The more hp you have the more each armor point will increase your ehp. At a certain level of hp, stacking armor/mr can be more cost efficient than getting more hp?
