I'd really like to know what on Earth may make you or FDev think that the game can benefit in any way from making AX-equipped CMDRs unable to fight back human attackers.
Sure, and by this logic crossbows that were invented to penetrate steel armor should be totally useless against leather armor. The big guns that were invented to damage ironclads should be completely useless on wooden ships. Shall I continue?
The issue here is those supporting the AX Taipan before the fix have no clue what you support. That little beastie had a 30% damage bonus on the fixed multi Condor's damage...
And please, enough with the 'realism' analogies. If you wanted realism, the bullets would leave the gun and ship velocity + projectile velocity. Obviously a great deal of the game is balanced around player interaction.
Oh, and every other AX weapon is also crap against players... hence the Anti-Xeno designation and all that.
