Thought this was fixed in Pegasus, but I have that skill delay for...heals and maybe the occasional other skill (sleep cloud, especially). I don't notice a delay when I play spear champ. Someone told me that mages might also have the delay, but I cannot confirm this as I haven't had a chance to play my mage. The delay is pretty long, maybe between a second and three seconds. Heals are maybe more on the one second delay while sleep/sleep cloud has a longer delay. I asked a couple other clerics and they said they also have a delay, so I'm pretty sure it's not just my comper being laggy (played this through Parallels only so far) or the 'net being slow.
Will have to see if I still have the delay on a proper Windows machine and good 'net when I get home in a few days.
