I think his abilities are lame because there are standard abilities.
Here is my suggestion:
Ability 1:
Deadly Strike: The same affect as in the beta but with new special effects (bleeding)
Ability 2:
Warcry of the Furbolgs: Every Furbolg in Range will gain higher attack speed, armor and more damage output.
Ability 3:
Nature aura: There is a Chance of 5%/10%/15% that emaron and his allies (in range) will be healed by some Hp if they are attacked by enemies.
Ability 4 (Ulti):
Earthspilitting claws:
Emaron uses his claws with such a mighty power that the enemies get paralysed (+damage). The earth under the enemies is splitted, slowing and damaging them for a few seconds.
