If anyone knows my squad they know when there's one me109 around, there's gona be a few more behind.
Myself, Kill3m, TilDeath, ZooZoo reguarly fly and cover each others 6's, but we do have a rule of thumb, one on one your on your own.
Helps develop fighter tactics and situational awareness. Only time I ever break from this is when I see someone I dont know dogfighting someone
or even two at a time and I ask him for help over vox range, this generally lets me know if he needs help.
I have a few one on ones with betty and others that ended well even with friendlies trying to dive in for the "pick" however
it ruins a good one on one because now the other person is damaged or killed by the sneaky help.
