Too high current will make the brushes crack and snap.
The motor still works since they are spring-loaded and wear down into shape again.
So I would go with the too much load too.
11.1v, if you are running a highspeed gearset or even a standard one with M120 spring, it can cause issues.
Bad shimming, or if your mechbox uses bearings, a broken bearing will put a LOT of extra load on the motor, and make the current up to 3 times what it should be.
Active braking MOSFET also wear down the brushes really fast, because the torque is reversed, and the brushes have to "reshape" every shot.
As for the water running (does not have to be distilled, in fact, it's better to put a little friction alcool, as pure water is VERY oxidizing), it's really not needed.
For a RC car that empties a 5000mAh pack in under 7 minutes, it is important.
For an AEG that uses a 1200mAh pack in a whole day, not so much.
