How to trivially defeat anti-shield weapon equipped fleets

[Q]

Zanthis which Version you used??
I cannot reproduce your results neither in Version 1.78 nor in Version 1.49. The shield depleter never had an effect on shielded fighters in my tests. In the combat simulator I do not see the detailed damage results you report. Only when a fighter is destroyed the shield value drops and the damage taken increases by the value of this single unit. Did you do your tests in real tactical combat??
