Another week, another article dealing with the math behind the scenes of World of Warcraft. Last week, the discussion focused around caster haste; this week will be a continuation of that as we delve into the world of melee haste. Haste follows a pretty different system between spells and melee attacks. When it comes to casters, haste influences how fast a spell is cast as well as the GCD for all abilities, allowing for the standard 1.5-second GCD to be reduced to 1 second. Haste for melee attacks, however, only increases the swing timer of auto-attacks and does not reduce the GCD on physical abilities.
This has created a pretty big disparity between how melee value haste over casters, with casters generally favoring haste far more than melee classes. Blizzard has attempted to equalize this in some ways throughout Wrath of the Lich King by increasing the amount of haste that melee get per point of rating, yet that really hasn't made much of a difference. Cataclysm will attempt to address this disparity once again by increasing the resource gain of melee classes through haste. Obviously the finer points of this mechanic are not known to the community at large yet, and it is unlikely that Blizzard has the system fine tuned at this point anyway, so this article will not address that fact. It is something to remember for the future, though.
