Izuel.....Izual's bro? Heh.

Deadmines can be tough in the early levels. I'd wait until level 22 to run it. Some of the blues that drop in there last all the way until you ding 60, it's hilarious.

I'd definitely not give up, if you're not on RAF, instance leveling is the most fun way to hit 60. Getting practice is really all it takes, I always had several deaths my first run through any instance on a new group.

You might even wanna roll horde instead, they have much better instances to choose from, and a super easy one off the bat at level 10 that gets you some great practice. Wailling caverns is fun too.
