Not sure which class to pick -- Looking for guidance

Don't expect to tank well unless you're twinked as a monk. You will be struggling to hold aggro in groups. Warriors do at least have taunt. SK/PAL got that snap aggro which is why in almost every group on the road to 60 you will see a knight tanking.

In 90% of the cases you will be the puller as a monk, 10% you'll tank waiting for a knight/warrior. Which is fun. You get to learn how a zone works, how it looks, which will make most other characters you roll more fun.

You won't be this super-class some prop up monks to be. If I had a choice between an equally twinked monk or knight, I'd choose the knight every time. Monks are great DPS and Pullers and CAN tank if you can't find a proper tank. Be sure to ask for someone to root if you're going to tank as a monk because otherwise the mobs WILL ping-pong and the healer will have to keep 5 people alive rather than one(which drains mana fast).

Mini-rant here... I HATE HERO MONKS WHO THINK THEY'RE THE TANK. Seriously, stop it. You're wasting my mana, you have FD, you can manage your aggro. Stop waving your T-staff shaped E-peen in the face of everyone, just stop it.

If you duo with a shaman you can't go wrong with either warrior/sk/monk, where the monk edges out the other two due to the combination of DPS/Pulling(splitting mobs)/good-enough-tank.
