I was once in a match flying a squid, when an enemy squid was up against a building in Rumble. Using the quick decision making skills I poorly pretend to possess, I decided the best course of action was to ram them full speed and crush them against the building. Assuming I had the speed advantage and we were the same mass, not to mention the building would deal extra impact damage to them, causing them to explode (hopefully) well before my armor expired.
It sounded good on paper. In practice this caused us both to explode instantly. This was also during the birthday celebration, so it was kind of awesome, but still kind of embarrassing.
