Other upgrades not quite as easy and/or as beneficial... Elda can make the T9 equivalent chest piece (Lunar Eclipse Robes) as well for even more crusader orbs if the two of you are loaded. There is a neck upgrade (Evoker's Charm) for 19 downgraded emblems. Same ilevel, but not PvP gear. For trinkets I'd go with the 50 emblem (Talisman of Resurgence) and then make the 60 frost emblem (Purified Lunar Dust) the priority. Back is a horrible slot to take care of. There's a frost emblem option (Drape of the Violet Tower), but I don't really care for it. Maybe after the trinket.
Gloves She's still wearing a blue quest reward there. Simplest fix is the T9 gloves for 30 emblems. Max 6 heroic run. If she runs them with us we can do this in 90 minutes. Boots Her crafted boots can be replaced with: 18 Heavy Borean 8 Arctic Fur 40 Icy Dragonscale 6 Runed Orb The Boots of Wintery Endurance aren't top of the line, but a 2 tier upgrade with few alternatives that aren't drops. Most of that can be farmed from the drakes in northern s. basin. Elda can make these. She even has the mats for them now for an IOU. Legs 50 emblems for T9, probably less than 2 hours grinding heroics. Bracers Replaced with: 20 Heavy Borean 6 Arctic Fur 12 Eternal Life 4 Crusader Orbs Moonshadow Armguards are solid, but the crusader orbs aren't terribly cheap. Elda can make these as well, though I don't have the orbs in this case to front the item. So, take the kids for a few nights and we'll get her squared away. :-P
Gearing up Hreidmar... I don't slot the DPS raids, so take this for what it's worth, but while I would have no desire to exclude Kris from anything the group does, Hreidmar's gear puts any raid she is in at a distinct disadvantage. I don't think it will reach the point where Tim says she can't come because of her gear, but I doubt she wants to be a drag on the raid either. So, I looked at her profile and tried to figure which slots needed the most help and could be taken care of fairly quickly...
