When they go in dive mode, spam your right mouse button!

or the period "." button. thats what i use. I find it more reliable.

a single click is for the target lock,
then you need to double click (or spam click) when they get close to the target to drop bombs.

having low lvl bombers makes it a bit harder, due to aaw, but they should be hitting like normal bombers.

try approaching your targets from behind, usually works better. 

don't forget to put enough bombs on the ship for multiple waves. 

If u autolock the DBS on target from too great a distance, your target will
have time to overheat and try to zigzag causing your bombs to miss.

Fly close, watching the planes shadows.   Your target will often think you are
perhaps fighters or you are after another target.   When the planes shadows get close then
auto lock the DBS on target which will not have much time to OH or turn.    When shadows get on the ship....spam the right mouse button.

It seems that having a full compliment of vets and experts will help you get hit and also reduce the effect of AAW.

Good luck

Thanks all for your inputs! i'll try this when i get home from work.

Don't bomb perpendicularly.

Having more experts and vets would mean more AAW resistance, which would also mean you would have better access to lower altitudes over the enemy.

This is also tantamount to saying: You bombs won't miss (or will rarely miss) since you can use low-altitude bombing (low altitude = less damage, but less time or no time at all for the enemy to dodge).

But I beg you NOT to do this on obviously AW'd L2s. You'll recieve eternal scorning from me. 

If u want it to drop SPAM it like your going to win a million dollars and press the drop bomb button too.....i press both to make sure it drops and it always work:D
