DEMON HUNTER! I love it, the weapons are great, and the Havoc Trait is a good playing style.
I absolutely love the starting quest and working with the broken ones, (they are my favorites) although my man prefers the Shiva's.
It has taken me a while to write an update on this as I have been so busy playing it. I bought the pre-order and played a tonne of invasions, mainly for the Armour, although I was lucky enough to gain a few weapons for my characters too. I created an alliance Demon Hunter, Bumped my druid up to 100 with crafting skills upgraded to 700 and then left her until launch day. I paled my Demon hunters story line until she hit 100 and then started to level my alts.
I have currently played through the invasion on Dalanaar and am headed to Stormhold, i get the funny feeling Silvanas is going to enter the battlefield at some point but only time will tell.
I was lucky enough not to have any issues with launch day, except a queue, but that was expected. Al in all from this side, it was a pretty successful launch and it has bee a good expansion so far.
