CTF is one of my favorite official game modes.
I've been playing it ever since I've started playing TF2 in 2012.
Sure, it isn't the best for engies, like at all, those poor guys trapped in the intel room, constantly, somebody go engie to relieve their pain, take their burden and make it yours, be a hero
but it's about as chill as it's going to get outside of mann vs machine.
You can't really join onto a TF2 server anymore and say "don't mind me, I'm just dicking around" but CTF seems to be that magical exception where almost nobody cares and the people who do are the ones that need to like
go play a different game mode
your iron ugc team means nothing to me
you're playing CTF
relax
