Here's the
cheap world of warcraft powerleveling that it's Saturday afternoon. I have my level 80 hunter around, and wouldn't mind running a Heroic instance for some dungeon rep or a little badge grinding.
But my more pressing need at the moment is to level up my paladin, and so under the current
cheap world of warcraft powerleveling here's what I do to get on my pally, log into cheap world of warcraft powerleveling on some instance I don't really want to run, like Sunken Temple, just so I can listen in on the cheap world of warcraft powerleveling chat while I level. Eventually someone jumps into the cheap world of warcraft powerleveling chat, asks for cheap world of warcraft powerleveling for Heroic Halls of Lightning.
Cheap world of warcraft powerleveling groups, of course, throws a wrench in that whole plan, because even with a citywide channel, there's no way for me to know that someone else on a different server wants my hunter to run a Heroic unless I'm logged in and waiting on my hunter. cheap world of warcraft powerleveling gamble, of course, is that with a cross-realm system, there will be a much bigger pool of dungeon runners to run instances with, and instead of waiting around on my pally until I find a group, I'll just choose an instance for my hunter, get into one right away, and run whatever I want any time.
