A friend and I just finished leveling out first characters to 70. We both chose rogues, which means we roll for the same gear, and have a lot of trouble getting into the same groups for 5 mans.
Because of this we have rolled new characters. As we want to do a lot of instances we decided to go with a tank and a healer. He rolled a warrior, and I rolled a priest. I have a shadowpriest at level 40 who I love, but she is on a different server.
My question is, given that the warrior will likely go arms or fury for leveling, and prot later, I'm after advice on how to spec. I am definitely going holy/disc later in the game, but its a long way from level 8 to 70.
In the mean time, is shadow the best spec? Coming from leveling a pair of rogues, things are taking an awful long time to die, so I'm thinking that if I dps we will level quicker.
