Hero stalker is giving 2 essence even if only hit 1 hero, but to be honest is ok bcs the original idea of making it give 0 essence vs 1 single hero was a really bad idea.
And dehaka’s Drag still dont stun the Sky temple miniboss even if any other kind of stun work on it.
I have some feedbacks after being main dehaka for 10 years in high elo:
Enduring Swarm & Pack Leader: The armor upgrade in Pack Leader is appreciated, but for god sake make the dehaka armors bonuses stackable or enduring swarm is going to dissapear.
Hero Stalker: if you dont want to make it give 2 essence if it hits 1 single hero it will be better if you turn back the talent to the last version and after that you must put a cap of a maximum of 3 essence instead of 2 (1 hero hit = 1 essence, , 2 heroes hit = 2 essence, 3 or more heroes hit = 3 essence). This may look “not balanced” for you, but this talent is usually used in a w dehaka, and a W dehaka sacrifice any option of flee for more sustain, is like a sonya with no jump and no speed, if he enter to a TF or if he is ganked he will stay until it dies, but at least sonya will heal for any heroe hit by the Whirlwind and have no mana cost, unlike dehaka who will burn all of his mana in a single tf.
The other talents are working fine for now
