Now that we're in, and I've played, I already am frustrated by Covenants. I really dislike the overall best one for DK (Kyrian) but a significant amount of power is locked behind them, so now I'm stuck with the most boring main group in wow I've ever had the misfortune of having to work with. I really hope they bring the other covenants in line with one another better, or allow us to choose the abilities we want while not having to be stuck with a group we abhor.
