All retail guides advice you to stack haste resulting in more/faster maelstrom procs.
On molten we get much more windfury procs due to the icd being individual for mh/oh which results in more/faster maelstrom procs making haste less valuable. Windfury attack damage is based on attack power and as we're using x2 windfury attack power becomes more valuable than haste.
