Stop over pushing the point or objective

I can't tell you how many times I've been in matches where some bozos decide to over extend pass the point or escort only to die which leads us handicapped a player or two against their full squad to just completely lose. It's so frustrating. It gets worse still as they then are the first to respawn and instead of waiting for the full team to respawn they go in 2 or 3v6.....so frustrating and then they blame the healers
