At first glance your HIT rating is way high (263 is cap and yours is 422) however looking at your gear there aren't really any pieces other than the legs that focus on hit.
Your rings appear to be good candidates to look for replacements.
Try for the
Darkmoon Card: Greatness Tricket (Nobles Cards/Deck, ~4kg-5kg) or
Darkmoon Card: Death Trinket (much cheaper, ~500-1kg) if Greatness is out of reach; I think both would be better than
Titan-Forged Rune of Determination, although not sure what people think of Death vs Determination. Greatness and Mirror of Truth are terrific.
The leg enchant could be upgraded to
Icescale Leg Armor.
Since it appears as though you are on a RP server, not PvP, look to replace the following enchants - at least for PvE content - if you mostly PvP then maybe not?
Arcanum of Torment enchant would be an upgrade to your helm once you reach Revered with Ebon Blade.
Get working on Sons of Hodir rep as they offer the best shoulder enchant:
Greater Inscription of the Axe at exalted and a lesser one at honored or revered. Not sure why you are hated by them - can't recall if you start there and quest to earn the right to do the dailies - if so do that as you can make lots of easy money doing the quests too.
If you can afford it try to get
Scroll of Enchant 2H Weapon - Massacre or
Scroll of Enchant Weapon - Berserking on your weapon; Savagery is good but the above are better.
Your gems, especially the blue on your helm, could use upgrades to epics (~175g-220g each)for a boost in strength. Try the
Sovereign Dreadstone for the blue on your helm (+10 Str/+15 Sta vs Agi/Sta).
You might want to replace the +10 Stats
Nightmare Tear gem on your gloves for
Sovereign Dreadstone (satisfies the Meta and the Gloves for the crit). The two
Sovereign Dreadstone would cover the Meta on the helm.
Once you get to 400 Blacksmithing socket your gloves and bracers for more strength gems (
Bold Cardinal Ruby).
Expertise would help but the conventional wisdom is to avoid gemming/enchanting for it - instead concentrating on Strength.
For your glyphs, use
Glyph of Seal of Vengeance over Righteousness (Vengeance will add 10 Expertise) and for your empty minor glyph try
Glyph of Sense Undead for a damage boost vs undead.
Regarding your talents, most prefer to not use Stoicism and Divine Purpose in favor of Divinity - won't help your DPS but it will your healers.
