So I can be a clay pigeon for the OPFOR? LOL 
Nah. It's that you still have fun in the scenario environment at any skill level.
In the melee arena, fights tend to start at lower alt, tend to be more 1 on 1, and tend to result in 1 of the 2 guys fighting getting shot down. If one guy is significantly better than the other, or they are equal but one has a better plane, or one starts with a bunch more alt, he will typically win.
In scenarios, fights tend start at much higher alt, and are many on many. Fights don't always result in all of one side dying. Some folks get saddled up on, dive out, and the enemy doesn't want to follow the guy all the way to deck. Or a friendly in the area clears you. Or its a furball, and the enemy on you transitions over to another guy and off of you.
