I have seen a few ideas such as an ejector for the moneyball ring, but I had one today I wanted to share. It may be possible, it may suck, but hey, it doesn't hurt to mention it. How about a new hazard for the ring, like an electric shock that freezes you in place, that is activated from inside the spawn and lasts for just a few seconds, with a timer similar to the ejector? It would be especially useful for when a team is controlling your spawn exits and just looking for kills with no interest in taking down the moneyball. I played 3 matches in a row against a team of some people from the board doing that today, and was unable to get any of my team (a pickup group with constantly rotating players due to the ragequitting) to work together enough to be able to stand a chance of making it out. I hate the idea of ragequitting, and kept trying. I realize I am not a particularly good player, but I can normally contribute something to the team. The most obnoxious part was watching 4 of their pros holding our ring and not even firing on the moneyball while it was down. So yeah, just an idea of something that could give you a chance to take back the ring when the other team has you locked down.
I think a $0 ejector or freeze trap for the upper ring that can be activated from inside the spawn could be useful. It still would not prevent all forms of spawn camping but it would prevent spawn campers from always hiding behind the glass opposite the spawn's main entrace.
