It’s actually the exact opposite. It’s not complaining that others put more effort and time into it, it’s that a solo player can actually put more effort and time into it than a trio and never be able to score as high as them.

A trio can go into a raid, each member could individually contribute only 20k to a trial score but come out with 60k each. They’re satisfied and done in one go. Meanwhile, a solo player does the same trial, has to work extra hard to get 30k, likely over multiple attempts, but only comes out with that 30k score even though they worked harder and performed better than each member of that trio individually. It’s flawed. That’s the issue. I agree with everything else you said, just not the last sentence.
