Not entirely true. Shyv has some dueling capacity in her kit, and has that painful fire-spin move on her W that just creates a zone of pain around her. (Her chief AoE farm tool, kills mini-raptors pretty fast.)
Her optimal jungle pathing is Red-> wolves-> gromp-> blue-> scuttle-if-up-> krugs-> raptors. Her passive means she will most likely prioritize dragon ASAP (and she can solo it at level 4 if she starts with >/=75% health and both refillable potions and at least one smite [most likely chilling smite]) since she gets added armor and MR for every dragon her team kills.
Treat invading her in the jungle like you're solo-ganking a toplane bruiser, because she can also function in toplane position, but be wary because she could also invade YOU early to bully you in your jungle due to her speedy clears.
