We have found a good balance for the aftercast delay that a lot of skills have, due to us trans versing to the renewal casting system to better balance the OP skills of some 3rd classes such as warlocks and Suras. So there will be a after cast delay on some skills, that cannot be lowered with just stats (dex), and also items can further lower after this cap, but do have a limit so some skills will not be able to fully be insta cast for obvious reasons (EX: asura strikes everywhere being spammed).
