I have been to hundreds of battlegrounds, especially strand of the ancient. And each time i see people trying attempting to reach the first gate, be it blue or green. But on the way there get massacred by the opposing faction. Now the most simple solution to this, and what a few people might not know, is that you can simply drive the catapult straight in the ocean and drive on the bottom to the chosen gate. Enemies will be shocked by your skill and hopefully stop pursuing you. They will be slowed by water and damaged by you at the same time, since you can still use fire and ram in the water.
And that, is how you rush like a boss.
