I actually like the fact that a screamer bomber can sometimes force a fighter to behave less aggressively towards the bomber. Bombers die very fast anyway (except a certain few light bombers), and the only way bombes have to deshield a fighter is a mine - EMPs suck horribly and might as well not exist for the purpose of deshielding snubs at all.
Rock-paper-scissor thinking is kinda silly when "logging bomber" means: ok, you die to 1 figher, and it is just a question of "how fast" and how much damage you can do before the inevitable happens.
I do not see a reason for a change, to be honest.
The toned down screamers are doing their job.
