Most players know the quick entry and escape on Vortex Portal by rocket jumping from the side entry level to the upper level, jump pad to Flag level, then RJ to side exit jump pads...

Here is one which can give you a quick exit if the Flag is not well defended (usually at the start of a game).

wow I have to train the rocket jump from the flag to the center teleporter. Could be useful

i was on defence so all took everything from the base :/
