Landslide seems to be the default melee enchant.  But I can see that others might be as good or better in some situations. Hurricane/Heartsong for instance if haste continues to be a high value stat for us. Avalanche could be great for us depending on how Mastery works.  Mending  could be a boon to PvP
 
Boots are getting a lot of different options as well

The have added more options to the speed boost than just Stamina.
 
The most revealing thing to me is the talent changes. Its obviously subject to major changes, as several abilities they said they were eliminating are still there, but here it is for your perusal

New Enhancement talents:
 
Focused Strikes : Tier1 : 5/5 increases Stormstrike damage by 40%.
 
Ancestral Swiftness : Tier4 : 3/3 increases movement speed by 15%  does not stack.
 
Searing Flames : Tier6 : 5/5 causes bolts from your searing totem to have a 100% chance to set the target aflame  dealing damage equal to the impact damage over 15s. Stacks up to 5 times.
 
Totemic Vigor : Tier7 : 3/3 increase the health of your totems by 10% of your maximum health.
 
Improved Lava Lash : Tier10 : 3/3 Increases lava lash damage by 30%, and by an additional 20% per ea of your stacks of searing flames, consuming those applications.
 
I like the Searing totem changes. Extra SS damage is nice, and Lava Lash suddenly got a lot more interesting.  Totemic vigor is purely PvP, but ancestral swiftness is interesting. 15% vs 8% for the boot enchant. I'm guessing this will be worth spending the points on.
