Thats what the MA's are like on the weekends. Little skill involved. Almost a 100% crapshoot.
When you pack that many into such small maps balanced front lines would be 100 vs 100. We now usually have only 3-4 bases along the front lines so, conservatively and if balanced, each fight should be 25 vs 25. Now, go fly into a 25 vs 25 and see if you can use your skills. Probably for a few minutes. Even if you're the best in the game at SA and ACM some lucky soul is going to get a shot on you. If you're lucky you can get out and land once in a while.
Some will say... others have good scores... I can only surmise that they don't fly on weekends, they cherry-pick, they vulch or they remain in the safety of their hoards.
This has become much more like an arcade shoot-em-up game than an air combat game.
Just my 2c and no, I'm not going anywhere.
[EDIT] There used to sometimes be only 400-500 in the big maps when there was only 1 MA.
