Having good opinions like:
>the game should be challenging at challenging difficulties
>the weapons and stratagems should feel good to use
>the game should be fun
>they should fix the bugs
>they should revert bots AIs to have good aim
>instakills are acceptable at higher difficulties, if the attacks are well telegraphed and can be countered in more ways than one
Can't be invalidated, no matter the number copes you come up with.

Dogshit opinions like:
>the game should be easy at challenging difficulties
>the weapons and stratagems should feel bad to use
>the game shouldn't be fun for the sake of realism
>bugs and glitches are fine
>lobotomized bots AI are fine
>instakills are never acceptable because they are cheap artificial difficulty
Can never be justified, no matter the number of copes you come up with.
