I'm actually thinking about which is more useful for my weapon. So here it goes:
Assume following armor against a meele target is total: 100 (gladiators armor)
If opponent has base dmg 40.24 (max hammer dmg + 15%)
You'll be hit for: 20.13
Now assume you requip your +5 armor weapon.
You'll have a total armor of 105 (gladiators armor + weapons armor)
Thus be hit for 18.45
Here you can see the +5 armor different is 1.68hp
A +30hp upgrade will thus last you 30/1.68 = 18 hits before being useless
Another example.
Assume your farming meele creatures, how many do you usually have around yourself?
I'd say 15. Now assume their minimum base dmg is 17.25.
Now each do 10 swings at the same time to you giving a total of 150 swings against you.
So...
Equip 1 (Armor 100 + 30hp): Total hp lose: 1264.5 hp (-30hp)
Equip 2 (Armor 105) : Total hp lose: 1186.5 hp
Can see that equipment 2 has less hp lose by 78 hp.
Of course i've neglected high damages and armor penetration, so a +5 armor becomes more useful.
In conclusion from this. a +5 armor upgrade is good if your being hit quite alot as a warrior.
Any ideas on this?

No argument, no rationale, just an appeal to ignorance (and an ad hominem attack
). It is faulty logic to claim that armor is working all the time while health only works until its gone. Guess what? Armor isn't working at all against any attacks that ignore armor (smiting monks, necro curses, mesmer hexes, ranger poison, warrior's bleeding, elementalist's lightning), whereas extra life does help against ANY attack.
