So I just hit 60 today. Leveling in the new Xrealm zone environment sucks, especially at 55-60. Nineties camp you all day in blasting lands and hellfire ramparts and you can't quest at all.
It turns out that 55-59 is the sweet spot where DK's que up as tanks but don't have any AOE agro abilities. Two dungeons with DKs that could only hold single target agro and I quit dungeons. I managed to crawl my way to 58 by grinding a lvl 54 zone that was safe, then I trick or treated my way to 60 (while watching a movie on netflix). Finally, FLYING! Yay.
A consequence to doing trick-or-treats to 60 was getting honored with a leveling guild I joined. I hit Honored and 60 in the same quest in fact. I had amased a sizable bank account while leveling by playing the AH and selling leather, 8.5K at level 59. That didn't last long since I bought 3 heirloom pieces and flying. Total heirlooms i have is now 4, one weapon from darkmoon faire and 3 guild heirlooms from getting honored. Now I'm down to 3k gold. SIGH, off to farm leather.
Hopefully the pattern of ganking does not continue. I hope to be level 85 by next week, and 90 in two weeks.
