Which +Armor Would Be Better on a Warrior?

It comes down to +5 armor vs physical (+ Holy, Chaos & Dark damage) versus +5 armor vs elemental. Do I have to say it again? T_T

You know Holy, Chaos & Dark damage are from caster weapons only (no skills, with the exception of holy damage, but almost all holy damage skills ignore armor anyways), so they are essentially worthless.

No, the question was +5 armor vs +5 elemental - +5 armor applies to *all* not just physical. In fact, at least according to both wiki's holy, chaos, and dark are non-physical *and*non-elemental. Since they are fairly explicit on this I assume they have been tested though I have not done so myself (I've never found such basic and long term info to be wrong on the wiki, though I guess it could happen). If they are correct you are wrong there also as +physical will not apply to them (physical damage is piercing, slashing, and blunt), only the unqualified +armor would work against those types of damage as it works against *all* damage that is affected by armor.

Repeat it again if you really feel like it, I can always link to the appropriate pages.

*Sigh*
I know all that. I was actually the first person to point it out, in case you didn't read the first page. It's just that if you take off the +5 armor vs elemental from the +5 global armor mod, for comparison sakes, you get +5 armor vs physical, holy, chaos and dark damage. Edit: On the other side, if you take off +5 armor vs elemental from the +10 armor vs elemental, you get +5 armor vs elemental. Hence the "In short" quote from Jetdoc.
I guess some people will never understand. If you still can't get it by rereading the whole thread, I give up.

By the way, the question wasn't +5 armor vs +5 elemental, here I'll quote Jetdoc for a third time:
Where do you see +5 armor global in that quote? I think the problem is that you skipped the "versus physical" part, and don't know it or don't want to admit it. Feel free to correct me, although I will probably not reply back. If you were referring to the OP, it was +10 elemental, not +5. Note that Jetdoc forgot about the Chaos, Dark & Holy mods.

I wasn't replying to your post back then, I was replying to the one I quoted. If you knew that to be wrong, why post it at all?

You are right, some people will never understand - you can't deal with armor that way. What the two numbers come out to be and the actual spread between them is MUCH more important than what the net change is from swapping mods in determining what to use.

I addressed both cases (it wasn't clear exactly what was meant so I addressed both cases) - so lets complain about not reading whole posts FTW! I can requote myself if needed (waste of bandwidth), however just click back a few pages and read my post again.Feel free to quote jetdoc all you want but until you actually bother to read the whole thing I wrote it is irrelevant as I already addressed what you say I didn't.

There is NO armor that will efffect Holy/Dark/Shadow/Chaos damage, they are all armor ignoring as far as spells/skills are concerned.

Now if your talking about staff/wand dmg then they are not treated as physical or elemental damage though they do not ignore armor. This means that both elemental armor and physical armor will work vs these damage types.

As for the OP, I would suggest going with either Dreadnaughts/Sentinals/Brawlers for insignias and sticking with fortitue weapon mods. Brawlers seams optimal for PvE use where you will face a large mix of physical and elemental damage, however Sentinals is the better choice when in an area/mission/dungeon with elemental bosses or elementals that use high dmg spike spells.

I'm not sure where you're going with that. I might have mixed up my answers for Njaiguni Blaze with what I wanted to tell you. But go read your post (#32). You start insulting Jetdoc for something he never said (and I see no typos). Maybe send him a PM and ask him to explain it himself, because I tried 3 times and you still can't grasp it. If you don't do it, I will, because I don't feel like arguing just for arguing anymore when I know I'm right. I'm also pretty sure he knows that global armor affects both physical and elemental damage.

PS: The first time you quoted me (Post #40), was a message adressed towards Njaiguni Blaze, not you, and apparently he/she understood (based on his/her edit).
