Blizzard has given WarCraft 3: The Frozen Throne another patch update. The patch includes three fixes, two regarding the Hex spell.
Community manager 'Bashiok' also mentioned in the forum that they will be looking into changing the ladder map pool.
Hex will no longer provide a speed boost to a Hero if cast at the end of Metamorphosis or Chemical Rage effects.
Reverted the 1.25b fix, "Hex will no longer extend the duration of Metamorphosis."
Fixed an issue where some Mac patches could lead to disconnections during Battle.net games.
