Leveling to 80 before the next expansion

So, I'm trying to level my 73 Shaman to 80 before the next expansion comes out, but It's getting pretty annoying. I do mad damage since the last patch, 4.0.1, with my elemental spec, but at this level, none of the dungeons really have any good gear for me and I really hate wearing greens. I keep going to these random groups, and I have to say that it pretty much sucks because of course the players are using their alts, and I am so tired of crappy tanks that wipe the group and then leave. Then I have the misfortune of having a pvp server, so every time I start to get into a good questing grove, some jackass has to come down from a flying mount and kill me for the fun of it. Too bad realm transfers are so expensive, because I have multiple high-level alts. On another note, when I need a break from the grind of all too familiar questing, I go hunting for mines on my main, and that is a pain too. It seems like there just aren't enough titanium spawns in the northrend area. No matter which zone I go to, there are always at least five competitor miners and we're all searching for the 3 titanium nodes that spawn probably every 20 to 30 mins. I don't want to buy it for the ungodly prices on the AH but I really need it for recipes and to prospect. I realize that if it was more common it wouldn't be worth as much, but I don't want it to sell.

Corroded Skeleton Key

The Corroded Skeleton Key costs sixty Frost Emblems. It is a trinket that provides 228 stamina and an activated shield that absorbs 6400 damage and lasts for 10 seconds and has a 2 minute cooldown.

The reason I got this trinket for my warlock is arena and battlegrounds. This trinket is useless for me in instances but a great asset in pvp. I'm really happy with it, it took me a long time to get up enough Frost Emblems since all I do is the daily dungeon and the occasional VOA.

I usually only play my 2v2 arena team with my wife, she is a rogue, and I am a warlock. So nine times out of ten I am targeted first. This shield and stamina give me a lot of protection against getting instant gibbed against double mages and what not.

Plus I am affliction so my character is always gaining health from my corruptions, haunt, and drain life. If I am running low on health I will pop this trinket and absorb some damage while I drain life and get bonus health from the Death's Embrace talent.

Overall I don't know if its really worth the sixty Frost Emblems for every class, but I highly recommend it for warlocks.
