you tell us theres no specific way to play after telling us exactly how to play each class
that's because what you are observing is a paradox. it's like saying "there is no order because there is chaos." Yes there is no specific way to SKILL INTO characters because the game has already been designed FOR you around the parameters that define what specifically each character is capable of.
for example you might as well say "ooooo you said do whatever u want but i cant use shield wall on my archer, wtfux bro"
Flask of Frost is insanely useful for shutting down dangerous enemies like most chest guardians. Otherwise I mostly play her as a trap and poison cloud provider, then stealth behind strong enemies occupied by the tank (hopefully).
That does not work on Perilous. At all. Just warning you. Unless you literally run in circles dodging the Arcane Horror's projectiles.

If a class is potent on their own then chances are they will bring more to a team. People "care" because picking weaker classes can make your team lose on the run. That's not to say that more niche classes cannot be picked - but I would never, as an example, pick Katari for a Perilous run. Nor would I pick an Alchemist or Reaver, and I'd only pick an Assassin at level 20 with all the necessary passives to do well.
Choosing bad classes can directly make the team lose. If you make the team lose because you wanted to test a bad class, that makes you selfish. In any team game it isn't just about your enjoyment sadly - it's the same principle as a MOBA. You pick whichever class the team needs that you think fits the scenario. Succeeding is its own form of entertainment for many people, which is why so many people care about what specific classes they play.
I get the sentiment - and on lower difficulties I'm always open to experimenters [even though I usually have to pick up their slack] but that type of attitude simply doesn't work in competitive teams on higher difficulties where there's less room for error.
It doesn't make the team lose. It makes meat heads who only want to use DPS classes that are incapable of team support, lose. For example I connected to a Perilous run today, hoping matchmaking would give me a team I could run Necromancer with. There was no warrior so I picked Reaver, and I figured since one person had a mic it would turn out OK. Then when the game loaded I told them how things should go - the archer should draw aggro to a choke point, the keeper casts barrier on all four of us and the elementalist and I will be able to hit the whole mob at once. Instead they forced me to charge in like a chicken with my head cut off and die because I had to follow their zerg tactics, even though I was the last one in the room I still got killed because they refused to make a plan. Then the only guy with a mic decided to be a condescending ass and I left the party. It's like first of all, I'm running warrior for them because they refused to; more importantly you can't just run around doing whatever you want on Perilous without communicating with your team, you can't just solo mobs in perilous and abandon your teammates because if they die the enemy gets stronger and will kill the whole party. I didn't stick around to see what would happen because I knew it would be a wipe, I mean when you've got a Keeper that won't prioritize putting barrier on the warrior - regardless of whether it's a Reaver or not - there's something innately wrong there.
Yeah, so if you don't want me to use something or you're going to be a selfish person who doesn't play as part of a team, at least put a bloody microphone on and tell me so I don't waste my time. And I'll either leave the party or switch to whatever class fits the party. But don't start thinking there's no other way to run Perilous than your way, because it's not true. I've had Kataris stay alive to beat the final boss because I was a good Keeper and kept barrier on them, as well as the other classes.
This isn't a competitive game mode though, it's a co-op. I'm just way more laid back about team setups than 90% of BSN apparently. Only thing I get miffed over is not having the 3 class types for doors and people who don't try and use teamwork.
I'd rather have a competent teammate who sticks with the team, knows how to use their class, and has good situational awareness than worry about them playing "low tier" classes. You guys place waaaaaay too much emphasis on the class kits and not nearly enough on the individual player.
This so much.
I got berated for opening and clearing a treasure room instead of backing up the try-hard Katari running 4 rooms ahead.
He still finished 2nd. I lol'd.
If he did that on Perilous, and he's on PS4, I want his gamertag. The man is a hero.
