That's the case with any other air to ground strike. The problem with strafing is that by its nature you're going straight over multiple units, so it greatly increases the odds that you won't get out of that game turn alive, and the shots are harder than other attacks, so the odds of you achieving anything useful as you die are notably lower than with other attacks.
Gah, having a hell of a time with a tablet. Over to my computer with a real keyboard...
Yes to reiterate what I so slowly and agonizingly edited above after realizing I initially missed the point of your question:
As for strafing vs striking: it depends. Striking is easier to hit, but strafing is the counter to mopping up multiples of artillery/IF that hide behind terrain and forefiet move. They're both upstaged by bombs tho for anything with a minxy TMM...
Strafing does have its advantages, but they're very niche*. If I'm out of bombs, 9/10 times a Strike is the correct call. Of course if I have bombs, 10/10 times bombs are the correct attack.
*The errata I mentioned upthread goes very far in making strafing viable. You can lay down your attack path in the back arcs of your victims, then offset your strafe template to cover the targets that won't be allowed to shoot back (unless they have TUR or REAR specials)
