I am of the opinion that the auto attack speed is just fine. I would hope that they will consider more variety of ability animation cancels. I find that battle duration is a bit too low (battles are too short) for a lot of abilities, actions, and classes to realize their full potential.
I would say though playing a lower level MRD is quite wierd/odd. At higher levels i'm pretty busy launching other normal strikes, buffing, debuffing and activating abilities left and right, but that's because i have a lot of abilities at my disposal. I can see if you were playing a lower level class you would be at a dirth of shit to do.
