Don’t even bother leveling a non meta class, you aren’t getting a run if you don’t have friends to run with or you aren’t the tank.
You just aren’t.
I tanked all the way through Wrath and i’m telling you from experience, if you are not a preferred spec, without LFD, you are never going to see the inside of Heroic dungeons, much less raids.
Be prepared to meet me on the bank steps and be inspected and told straight to your face your gems suck, you are missing enchants, and you still have quest greens.
Welcome to pre LFD, it’ll be your classic Wrath home now.
You will be at the whim of your tank, they will form the run, dictate the pace, and if you run ahead and pull, or act up, they will Blacklist you, and your wait times will get even longer.
I used to keep a literal list of names on a piece of paper right beside my computer of people who I would NEVER run with again while tanking.
I did this because when you have to manually take the time to set up a group, inspect the members of that group, travel to the dungeon, wait for little Billy to finish his dinner or go potty etc, if we get in there and you cause problems, you ain’t coming back.
I’m not saying this to be nasty, I loved LFG, still do, but this is to remind some of you that grouping was not sunshine and rainbows before LFG, it sucked.
