Why did they keep bringing back Leeta?

Yes. Maybe put in as eye candy, but her acting ability carried her farther.

Bashir gets dumped wearing an old uniform in s05e07.

The new uniforms showed up in s05e10 Rapture.

Prison Bashir in S05e14 is still wearing the old uniform.

Yes, Bashir was dumped before Rapture (Episode 10).
But not before Let He Who Is Without Sin (episode 7), the episode in which he was dumped.

The only episodes before that two-parter we know for a fact it was Bashireling is "RAPTURE", "THE DARKNESS AND THE LIGHT", "THE BEGOTTEN", and "FOR THE UNIFORM" (though he didn't appear here). The uniform Bashir wore in the prison makes this clear.

Bashir was most likely taken between "THE ASCENT" and "RAPTURE". There would be too much time in-universe to go by for Bashir to be taken before or during "THE ASCENT".

That explanation is plausible.

I can think of two big reasons...

Quarks remark about hiring her for her 'brains' always made me LOL.
