So I've been playing ninja for awhile now and haven't experience any of the issues described in this thread, but I'm curious about a few things.

Can I just click a mudra combination all at once and click ninjitsu and then just wait for the server to do all the ninja animations for each button and then cast the ability? Or is there some delay that I have to wait for? Normally I just do it slowly to avoid it thinking I did it wrong, but I don't actually know if that is necessary or not.
