I'm thinking of trying out Cyclone with my evasion/DW block build but obviously I won't if you're unable to evade or block while in the Cyclone animation. --- Please change your vector and move to a different coordinate because this quadrant is off limits.
I'm assuming the answer is yes based on what I've read in forums and people specifically making Evasion builds around Cyclone. It should be like every other skill where you can block/evade during the animation. The animation for cyclone just happens to be as long as you'd like it to be. --- http://img.photobucket.com/albums/v208/Link7899/168b9ce6.jpg "Only Hell can cleanse what we do."
