They could have at least written different lines for different voice actors.
Or, if budget constraints are the factor, at least make the your single line not a "joke".
Seriously, I'm such a freak about these things the first thing I do in every game is swith out the voiced unit acknowledgments and barks because I can't stand the repetitiveness. Here I couldn't switch it out because you need the voice cues for secret walls. I was suffering like a fucking carthorse.
