Since Team DM was introduced, I have always wondered about the enemy bases. Why did they not put them right against the corner of the map? Can you go around them? Well, a few weeks ago, I tried to go all the way around the base using the grey border without dying from the guardians, using the destroyer, right? The fastest tank in the game, at the time. I used this build: 5, 7, 7, 0, 0, 0, 7, 7. I got to about the corner behind the enemy base when the Guardians pushed me against the wall and vaporized me. 

I tried this experiment using the booster yesterday, it being much, much faster than the destroyer. I made it all the way around the enemy base and was escaping with about 1/10 of my life... when one guardian came back from messing up my overly-daring comrade and hit me once.

It would be great to see a video of someone attempting this... just hinting.
