Looking for a fresh experience so I decided to start on Frostmourne and cannot decide on what to play. I enjoy all 3 roles(dps/tank/heal), but currently I'm more inclined towards tanking.
I was thinking maybe I should play a pally tank. What do you think? Is this spec overplayed?
Also, would like to play on alliance, but I see that there are more horde players. Do I miss anything by choosing alliance?
It's overplayed because it is good. Since you are open to all three specs, that's a solid choice, especially given the Human Racial if you PVP at all. Only thing you will miss by going Alliance is ganking Alliance. I recommend making a Horde toon separately just for that.
