I saw some guy do an arena naked with one skill slotted - and wasn't doing any animation cancelling. So, I would say: Definitely yes.

Would it be possible to deal enough DPS on time (to bosses that have this mechanic) if we had to wait for heavy and light attacks to fully complete the animation, wait for every skill to finish too and also wait to weapon-swap?
What do you think guys?
Thank you.
