Dracoris

I only know how to play frost but make use of stuns and slows. A good combo is frostnova+blink to get away from the enemy. Many spells like ice lance and blizzard will slow down the mob. Make use of sheep.

Don't give up! It is a little painful at first. And yes, the graveyards are super inconvenient. Who knew death would be a pain in a place that is known for death! I would have thought it would be easier. I am not a mage, but my main is a priest. (1/2)

Gear will make a big difference. It's not your fault, it doesn't make you a bad player. That's just how it's tuned. I would buy some cheap gear off the AH or have a friend make some. There's so much fun to be had! I encourage you to push through!

Initial thoughts, probably as constructive "hide behind pally" , hide behind DK. Hide behind warrior. Bring healer friends. But in all seriousness, gear. Even if you have to AH ilvl 168, every point of int matters

There is a potion that will give you speed in ghost form. I have used it a few times. I agree though on being squishy. Invisibility is handy when too many mobs pull. I also ended up settling on fire spec as it felt better. I was feeling so squishy at the beginning too....

And honestly when we get flying it will be a game changer. Revendreth is the worst for trying to get around and all the mobs in the pathways. Ugh. So much hate.
