Elitists tend to actually be good at whatever they're lecturing people about. But let's not pretend this isn't a bad faith answer considering you intentionally misunderstood everything I posted about.
You discuss positioning when there is no proper way to position in a lot of instances in FLs. For example you're in the middle of Onsal, and it's so easy for anything with massive aoes to put in work. I've pointed it out before, but DRK/DRG is just meta, and if that left something else would replace it. I also never stated that you get deleted, considering you should be able to prop up guard before DRG LB fairly easily and spam your recuperates til out. Doesn't change the fact that you were just pushed off the objective with such ease.
And my point about BH isn't about it being hard to get. It's the snowball effect from it. When half or more of one team is just there to level alt jobs and farm tomes, that snowball effect becomes menacing. It means that you can't do anything with even the small group of players that are there to play.
This is why pre-mades and organized parties are a nuisance. If FL was more like CC everyone would be rolling the dice on whether the team is even interested and will work well together or not. There'd be more natural openings. It'd be more of a level playing field even if half your team is afk hitting a rock themed target dummy while a big objective is up and the other two teams are fighting. This is the heart of the problem.
You probably haven't. I mean haven't you heard the term solo carry? The only shooter I ever played where I actually had to communicate was OW. CSGO/PUBG both allowed you to carry your groups if you were good enough. MOBAs are the same to a degree. Obviously there's tools for sharing and communicating there, but that's just quick hand communication. That's not the same as roleplaying general.
