, not attacking from the 6 oclock is VERY difficult and 1 to 2 minutes to setup is a joke right.
No it isn't "very" difficult.
Oh, it's more difficult than attacking from dead 6, but almost all the time the bombers are flying straight & level at steady speed, so it's actually much less difficult than attacking an enemy fighter. The only time it's getting really difficult is at very high altitudes (20+ k), but most bombers are flying way below that.
And of course you shouldn't attack to kill a bomber with each attack - that would indeed be difficult, but you don't have to. The main advantage of slashing high-speed attacks is that you will live to try another one. A simple-six attack (tm)
seems easier because of the higher probability to kill 1 bomber before you go down, but other forms of attack have a much higher chance of getting all three of them.
But like all things, it has to practices a bit. If you are not used to it, you may collide a few times before getting some feel - but it's not a thing that you have to practice for months to get any amount of success.
And regarding the "2 minutes are a joke" - Most fighters are at least 100 mph faster than the bombers. 100mph means 5k yards
relative distance gain in 2 minutes.
