You have countless video and text guides as a starting point. I mean, where do you think the guides come from? Players go in when the content is new, run it, figure out the mechanics, and eventually clear it. You don't have to know what's going on the first time you go into any given encounter in order to eventually clear it. Does it help? Sure, absolutely. It cuts out a lot of the trial and error when you aren't trying to figure out how everything works, but instead are trying to execute steps that someone else is walking you through.
It's not a matter of clearing 5%, 10%, or even 20% faster. It's the difference between actually doing what the party was planning on (farming) and wiping to mechanics over and over because one person doesn't know how to do them. We're not talking about Neverreap or St. Mocianne's here. We're talking about content like Coils (even unsynced there's some things you can't ignore) and the recent EX primals and Alexander Savage where doing mechanics incorrectly spells death for you and quite possibly your entire raid.My FC is very helpful, and I know that with time I can get the things done, so this isn't a thing I would personally do. I am in no hurry to jump in with a bunch of people who care more about clearing 5% faster than being patient with someone who may have done it a few times (or on another character) but still isn't great at it.
The fact of the matter is, when people lie to get into a party we do tend to think negatively of them as a direct result. Those people end up on my blacklist because I don't care to associate with them. That single act of deception shows blatant disregard for the other seven people in the party and what they're trying to accomplish. Basically, you're shitting all over them in some selfish fit of pique and saying, "I'm entitled to have a first clear because I pay $15/month and you're going to get it for me whether you like it or not."I'm just trying to say, when you say things like "I might even start thinking bad of you as a person when you could be the coolest person to be around." you drive away future players that might have bothered to learn a fight enough to farm with you, because, frankly, that's a crappy attitude.
Yeah, how about no.
