Not sure if this was discovered already. If you grapple an enemy player onto the ascending stage before dropping down into the play field in Huttball, they die automatically or if you Jet Charge onto the enemy's ascended stage, you die. I did this once to a player holding the ball right before he crossed the endzone and he died and I received the ball without the opposing team receiving a score. Your time is obviously limited though because of the desertion timer. Thought I would share this discovery and let you all test it out if its the same with you.
