Prior to this patch, when you were doing a weaponskill or spell, before it was about to finish, you could hit the next skilll and it would say "Readying [skill/spell]" and would start it up right when your first one would finishe.

Now it seems that I have to wait a good second or two the moment the first skill/spell finishes before I can start the next. A lot of times I hit the button too early, causing nothing to happen.

This reminds me when the "click spell, then click name on party list to start casting on them" disappeared for a patch.
