Sorry for invading, guys...
But I HAVE FOUND A WAY TO NOT BE KILLED RELENTLESS BY DAVY CROCKET!!!
Here goes the guide:
1 - Manage to be on a BTB or BTC game against him, just you and him, nobody else;
2 - When you manage to bring him down, let him tank, and keep your way to the red base/ship. Dont look back!!!!!;
3 - Bomb the Davy's base and autodestroy IMEDIATELY!!
4 - Try to kill his tank after respawn before he does his job. Well, you wont accomplish this last part, and you will probably lose the game, but at least you will not be killed by him relentless...
I hate you, you bully!
