Hey.
I know Dragon Roar is the better choice for single target damage, but I'll be running CMs on my Warrior soon so I'll be running with Bladestorm most of the time and may not be able to switch talents quickly enough before a boss fight. So, even though Bladestorm is less effective than Dragon Roar in a single target scenario, would it still be worth using?
Thanks for your time.
Edit: To specify further, I'm playing Arms.
