I've been hard at work getting him better gear and enjoying having a third 80 (although his server isn't my favorite... I'm not sure what I'm going to do about that, though). I've run some dungeons at 80 and have managed to get a couple of lucky drops and some quick upgrades via the Auction House and faction vendors.
First and formost, I was most excited to join a random group into the Coliseum at the Argent Tourney grounds. As the only Plate-wearing-DPS on the run, when the Helm of the Violent Fray dropped, I had no competition. Bingo, one meta-socket helm for Purah. This spurred me on to get a few more upgrades, namely so I could buy, socket, and activate a Chaotic Skyflare Diamond into that pretty, winged helmet. I visited the Auction house to buy some strength + hit gems (I'm still woefully under the hit cap, unfortunately...) and a belt buckle, and then traveled around to some vendors that had shiny things to buy.
First stop: The Argent Tourney, and the Silvermoon vendor. As much as I really, REALLY want the Silvermoon two-hander for 25 seals, I can wait a little longer, and instead used up half of my Champion's Seals to buy the Clinch of Savage Fury. I considered buying the necklace that's available there, too, but I think I'll wait just a little longer. I mean, I REALLY want that sword, and it'll take a few more days to get it, the way I get seals (i.e. slowly).
Second stop (after a few more quests): The Shadow Vault. As a Death Knight, I had a slight head start to my reputation, and finishing up the quest lines for Darkrider Arly at the Fleshworks, along with a couple for the Bone Witch, and I was Revered with Purah's true faction. I immediately visited in order to get a Runeblade of Demonstrable Power (to tide me over till I get the Argent Tourney sword of awesome) and the Arcanum of Torment to put on my helm.
It's a start. I still need more hit. A lot more hit, and I'm really sad that I can't put a Titanium Weapon Chain on my sword along with my runeforging. I love the weapon chain. *Pouts* I got a couple other items while I was running errands for the Ebon Blade, and it's possible I can pop a few more +Hit gems onto my gear. I keep thinking that I just need to run some more of the Level 80 dungeons, though. I don't want to even try Heroics until I'm at hit cap. I don't feel it's fair to other players to come under-geared and expect to be carried through the content (plus expect to be allowed to loot), much less have some healer blow mana on trying to keep me alive in content I'm not technically ready for (and yes, I know that Blizzard has a gear check for Heroics, but, seriously, I'm nicer to other players than that).
Oh, and by some luck of the draw, Je'Tze's Bell dropped for me as well during my questing for the EB. I'll pop it up on the Auction House soon enough and see if I can't get some gold to cover all my upgrade expenses.
