Some ideas about Azmeri Wisps

The current Azmeri Wisps make me have no desire to play. Wisps often put me in a dangerous situation, and it runs very slowly. I have some small ideas.
When players first enter a map, Azmeri Wisps will randomly possess a rare monster. Thereafter, it will attack units nearby without discrimination, killing them to seize their power and enhance its own rewards.
What do you think of this idea? Of course, it's just a random thought of mine. Please ignore it if it's not reasonable.
