With scheduled weekly maintenance (7:00 a.m. PDT, Tuesday, September 28 in this region), Spell Haste will now lower the global cooldown (GCD) to a minimum of 1.0 second. It has been possible for players to approach a minimum of 0.75 seconds since Burning Crusade Classic launched.
This hotfix is intended to bring the behavior of the GCD in line with version 2.4.0 of Burning Crusade, which the gameplay conditions of Burning Crusade Classic 2.5.2 are based on. Due to a bug in the original 2.4.0 code, players with high Spell Haste in original Burning Crusade were sometimes able to cast certain spells less than second apart, and they would also sometimes be delayed to over a second, based on how their actions were lining up with the server’s tick rate.
With this hotfix, we’ve decided that the fairest and most accurate thing we could do is to replicate the intent of the original game and enforce that Spell Haste cannot reduce the GCD below 1.0 second.
Thank you for all of your feedback on this issue.
