Confusing topic, is it a bug report or a feedback?
Either way, its an intended feature for Abomination to "fall down" when one of his 3 armor pieces breaks down.... Which added quite a set of additional bugs such as:
- Gliding around and attacking players while performing stand-up animation
- Moving around while being FROZEN
- Instantly dying because Knockdown effect caused by his armor breaking down, occasionally clips him through the floor or a wall that causes instant death.
