I haven't really noticed it affect my gameplay much, aside from trying to quickly get in a pounce or a boom before it becomes AI.

However, I have noticed that I don't always see the "Blah blah blah is becoming the Tank!" box when someone else becomes the tank, which is a disadvantage to me, because sometimes I won't notice until too late that a tank is coming, and I'll die or otherwise be unable to coordinate with the tank.
