5cp sucks to spectate but it fuckin owns to play. a little bit of downtime here and there is really nice honestly and if you're having too much of it then you're not playing properly.
At this point most people play this game because of the way it's "supposed" to be played, the community's too small IMO to really sink investment into massive shakeup experiments (see 4s, Arena Respawn, Prolander, NR 6s). People have played with the flaws for years now and it hasn't really gotten more noticeable, so why try to fix them when almost every idea people (at least people with influence) have had for change has been bad?
I have a theory that highlander-brained type people cant stand 6s because they need something to be happening constantly, every single second, even if its meaningless. When there's a bit of a lull in the "action"—maybe even ubers, just took mid, both teams waiting for respawns—they can't just sit and assess the situation, poke the flank, talk through next moves, or just take a sip of water.
Feels sort of like how people used to big modern blockbusters can't stand to watch slower or older movies, where there's not constant action, music, snarky dialogue, fat guys farting, whatever
