Hi Chasm.
Your gear is good enough for Karazhan, no doubt.
Your appliacation is also well written, simple, and you nailed the template totally. Good job.
On the other hand, your gear also needs some "Karazhan upgrading", but it's nothing you should be concerned of, it's good enough atm.
What I'd like is that you're not dependant of Karazhan to improve your gear, that's a great ability.
You're also abit low on Heroic keys, but that's nothing we can't work on.
I'd like to have a little talk ingame with you, so throw me a whisper.
