Heavy Armor options

[MithrilSoul]

Hi all,

My pally is currently lvl 10. (Technically a 9 pally/1 rogue, which I am kinda regretting that rogue level about now and will eventually LR+1 to a pure pally at some time, but that's besides the point.) She is a THF build, high STR, high CHA, low DEX. I'm looking for some suggestions for heavy armors progression as I continue to level.

At first I was just using full plate of the highest + I could find. Then I discovered the joys of DR, and for a long while have been using a +2 full plate of Invulnerability. However, now that I am level 10 I am encountering more & more mobs that seem to be bypassing the DR 5/magic of the Invuln armor so I've begun searching for alternatives. I did pick up a +2 adamantine, but I find myself going back & forth as to whether 3/- is better than 5/magic. The only clear upgrade I've seen on the AH is Full Plate of Giants (5/-), but every time I've seen it the prices have just been astronomical (500k gold and higher). Even if I *had* that much gold (which I certainly don't), I must admit I find myself wondering if it would be a significant enough upgrade to justify the cost.

Where do I look from here? I did pick up (cheap) on the AH a set of Argenti's Plate (passive 30 fire resist) so I am set for those situations where I need mega fire protection. And I do have an armor with Deathblock (Bloodplate Armor) for facing those situations. But otherwise, I am not sure where to go next and what I could/should be either looking for on the AH or trying to hunt myself as chest drops/quest rewards.

Any of the veterans out there able to make some suggestions for the lvl 10-15 level range? I'm not VIP but I am p2p and have bought most of the "big named" xpacs (currently toying around in Sands and I recently took advantage of the sale on xpacs to buy Gianthold and Necro 4), and still have some DDO points leftover from my last purchase to buy anything I might not have yet if it would be beneficial to me.
