First of all, great build here! This is the reason that I'm back in diablo again, because I just had to try this one out. Of course, I was around level 50+ when I actually read that this was a PvP build (never PvP'ed before), so it might not have been the greatest choice for my first character (but who cares, right?).
In any case, I did some mid level dualling with this (crap resists though, making me a sitting duck for most elemental damagers), and I did pretty nice against most physical damage builds (except other chargers). Not bad considering this was my introduction to the PvP scene. Actually winning without much experience must say something about the usefullness of this build.
What I really wanted to say was the following, since this was mainly a defensive aura build, I was thinking about switching out charge (and might and vigor) for vengeance + elemental aura's to make this more PvM oriented. Vengeance also has a very high damage potential, you can kill anything regardless of immunities, and it's easier to use than charge in PvM. In addition, you can actually claim to have 0 points in the offensive tree which must be worth something

(as well as having +max resists from the single resist aura's). You'll be doing less damage than charge though, and you'll need some ias as well, but for PvM this would be superior I think.
Some other tips and tricks:
1) If you have trouble with getting some resists or reaching your strength requirements for a cryptic axe, then consider looking for a rare coronet/tiara with +2 skills, 2 open sockets and a nice +str bonus (and/or +resists). You'll lose out on 1 skill and some damage reduction, but you get a lot more freedom for you gear. Also, +2 pala skills can be very expensive, but +2 defensive aura's is pretty cheap (I got a circlet with +2 def aura's, +20 str, +20 energy and 16 resist all for free). The damage reduction can be cured somewhat with other gear. The same would go for the amulet of course, although maintaining at least one +3/25 would be a good idea.
2) Never forget Griswold's armour! It has low strength requirements (10x) and gives you +2 defensive aura's (!), +20 strength, and gives you three open sockets as well. In addition, you can get these for pg's. The sockets can be used for ber's (24% dr) if you're filthy rich. But I use them for 3xsheal. 3x sheal + bloodfist + verdungo's = 100% fhr. Alternatively, you can use Dols and Sols (+21 replenish life or damage reduced by 21) if you already have the fhr and want more life or want to make up for the loss of damage reduction from using a rare circlet/amulet.
3) If you want to (I'm not doing this btw), you can use a prayer merc as well, so that you have all three of the regenerate life aura's active at once. You can even give him the insight so that he benefits from the meditation aura as well. Just remember that his Prayer level (and thus the life regen from his meditation as well) is a whole lot lower than yours.
Thanks for getting me back into diablo with this pretty cool build
