I've seen it all now.
Saw someone on my enemies team playing Abathur...and trying to melee people with him during pushes. He would go INTO OUR BASE and symbote on someone....his cocoon out in the open in the middle of OUR BASE..
...yeeeaahhhh.
Though I think Ultimate Evolution should be completely changed. PERSONALLY I think he should "infest" an allied hero and just...extremely buff them and augment their abilities.
