@Shazz: Looking at your armory I was almost in the same boat you are about a month ago. I had to gear up really quick. You might consider a few upgrades at boots (the new badge one is extremely nice) and don't be so quick to replace your hit yet.
Since you're getting 32 hit from your trinket alone. Now it's a very trinket when you're low on hit, but what if you run into say Hex or even the new alchemist stone? Then you suddenly need to find around 20 more hit to be capped again or give up 40 potential spell dmg increase over 15 (by keeping your old trinket and replacing the icon).
Now if this other mage is remotely t6 geared (1100-1300 spell dmg, hit caped, 30% crit, and 4-5% haste) he can almost play suboptimal before you have a chance to catch up. Your best bet is do your best, stack CDs, flamecaps, destro potions on fights that's not mana intensive and pull your own weight.
