I'm gonna butt in and say this cause multiple people have asked.
Using Ned to aggressively overdefend like that isnt trolling. You practically get 20+ seconds of invulnerability if used right and is pretty much the "meta" thing to do especially if the Bart player is also doing it. In the clip you posted you hardly lost because of him getting swarmed, being unable to make the jump, and losing heal. When you climb the ladder you can see like half or more of the team being stacked in the corner on top not even bothering to defend.
Maybe if this was repeated behavior across multiple rounds it would be trolling but from just the clip you posted what he was doing what he should have been doing with an item like that.
