Positionals in the Open World

[Kahnom]

You should be able to get all positionals without a tank. Just stand as close as you can to the enemy's center, W through and instantly hit the back-attack as you're passing, or at a diagonal (WA/WD) and instantly hit the flank attack. I can say from experience that this works even at 300 ms latency, quite reliably.

As ex-300 ping player,i can confirm this.
Kinda tricky but possible as long as you ain't run out of patience.
