What's wrong with being concerned with DPS in farm groups?

I'll admit I rarely do ex primals and savage content myself, but my understanding is that in a farm group everyone is expected todish out their best performance with the objective of clearing the instance in as little time as possible with few incidents...

Plus "farm group" implies a multiple amount of runs - while yeah, it might be 2 or 3 minutes EACH run it all piles up after a while and it's less runs you're doing, right? :/
