S!
Finns call this tactic as a "Keinutuoli taktiikka" which means Swingchair tactic or Pendelum tactic. Paralel attack runs & hi-yoyos ie. As one pilot is attacking (Attacker) another pilot pull hi-yoyo (Support). Roles are changing flueltly.
Support responsible is maintain tally&visual AND sametime makea fast check to the near by air space if new threats are inbound. Both have prety good SA and E-state. Sometimes its better disengage together and gain some E.
If you find yourself in Finnish swingchair with Finns, its better read fast a pray which start with word... Amen.
Common 2vs1 mistake is that when both are attacking same time and even worst, if both continiously pulling horizontaly for the gun solution. Poor common SA and E-state. One higher con and sitution could turn fast to the 1vs2...
For the "Gangbangdweeps" whiners. Next time login to the DA for dueling... Big arenas are just too much for you..
