I wouldn't. Otherwise it would be grating to hear
the same voice line over and over again.
Still some lines are saying the exact same thing. And why does it have so much varity if it's voiceline you hear every few weeks?
Barely anybody who didn't watched the video will noticed that Pauling can greet you with different lines like:
"Scout, Pauling here"
"Scout, Miss Pauling here"
"Hey Scout, it's Pauling"
"Hey Scout, it's Pauling. Got a contract for you"
"Hey Scout. Pauling here. I need your help"
"Hey Scout. Pauling here. Think you can handle this?"
"Scout, Pauling here. I got work"
and a few more... similar for every character
Notice how some lines have other lines basicly included in them. And you need to be really lucky to hear this lines.... every three days. Where you can barely remember what she said last time.
You see, it's funny how they care that TF2 is now less bloatware by removing the custom maps after the event, but simultanously they add tons of useless soundfiles they are probably not going to remove.
Why do they even waste effort by trying to add varity to voicelines which you hear so
increadibly unfrequent?
