Nice damage man, but I'd recomend a better balance of stats. You are almost one shot material with that hp. My ret pally does that damage in mail, with 3k hp. One thing ive learned after 6 twinks at 39, its about balancing gear and enchants to get the overall best, focusing too much on damage or healing just doesnt work well. Its nice seeing high damage, but dead people do no dps. Hp is one of the best stats we have learned to get as a twink guild. The last one standing wins, doesnt matter if you have high or super high dps, if the other guy outlasts you cause he has alot more stam, he wins. And 1700 vs 2700 hp, means you have to have like 60% more damage than who you are fighting just to break even, and obviously you wont.
I dont wanna go over your gear completely, but after the stat changes to shaman you will use many of the exact same items as twink rogues and ferals, so check them out. You really need to be atleast 2500+ hp which is the norm for the average twink leather wearer. The rogues i play with are upper 2k.
Also, my next twink will be a enhance shaman as well. They are not that common in our battlegroup, and should be fun, i like not doin the standard specs, so maybe ill try some elemental or some odd hybrid too. Too bad I cant get a PoD on my server ever, atleast horde side, really makes weapons a pain.
