Tested two client, a 6/14/2011 and other 7/30/2010 and then I noticed a difference. With client 2011 skills as Jupiter's thunder, divine light, fire lances, ice, among other seems to have a fixed delay, even leaving the delay 0 the snowman attacks slowly. Already with client 2010 attack is faster, Jupiter's thunder, fast comes out well, Spears, and other skills. Now comes a doubt this is the client or in the source? I have for me to be in the client.
