Yeah just today this happened to me again. The difference is: unlike in the past, I actually have a capture card but didn't use it today.
I played RM in random ranked on Camp Triggerfish and the enemies were about to win, thex pushed early and I got to splat the RM-bearer midair above the pole, just 1 point away from victory, while we were still standing at 94. They kept us in our own half for a long time, but our whole team fought back and there was a situation once where I was certain I would die while jumping around bewteen two enemies up close (with my Custom Jet Squelcher!) but somehow survived. I would've loved to capture that moment alone. ^^
We tried to break free several times but they wouldn't let us. But we were even more resilient, so the enemies had to pressure us even more and take more risks. We continued to defend and eventually, less than a minute before the end, while the enemies were playing risky and all four of them were near our base, me and a teammate managed to sneak through... and I was able to carry the RM to the end! We won with 100-99! :D
