Jalal's Mane is a wise choice for any Druid build, regardless if they specialize in Shape Shifting Skills or Elemental Skills, simply because the bonuses to Druid Skills, Faster Hit Recovery, All Resistances and Strength are all useful.
This unique helmet is even better for Werewolf users because of its bonuses to Attack Rating and Shape Shifting Skills, although these builds may still find Cerebus' Bite to be even more helpful for Player versus Player since it provides a much higher bonus to Attack Rating and causes Open Wounds. For Player versus Monster though, Jalal's Mane is still one of the best options as its more balanced.
Jalal's Mane is considered to be the second best helmet by many top players for Wind Druids, even if the melee-oriented mods appear to go to waste. The reason is that Wind Druids do not need much mana due to the low casting cost of Tornado, which makes a helmet like Harlequin Crest slightly less useful.
The best helmet for a Wind Druid is not a unique, but a Rare Druid Pelt with +2 to Druid Skills, Faster Hit Recovery, Life, 1-2 Sockets (which can be then be used for All Resistances, more Life and/or more Faster Hit Recovery) and +3 to Tornado. While such a pelt is superior, it is quite difficult to find and Jalal's Mane can be acquired very cheaply in trade with other players, making it a good temporary option.
