Ya know, the funniest thing is my fc has two high end statics: No Hit and Columnae Custodes. Both were formed independently of each other yet happenstance has at least 3 members of No Hit (a world prog team) and 5 members of Columnae Custodes (a week 1/2 tier team). If we really wanted to, we could probably field an entire static with our in-house members, but A: we don't want to, we have different goals for raiding between our groups, B: it wouldn't change much for people in our fc, as our top members would all have filled out exactly one static, and C: not everyone in our fc wants to raid.
You see, our fc is a meme: we're casual oriented to the bone despite some of our heavier hitting members. In our group, we don't do too much to advantage raiders besides scream support for them on stream.
We have map nights, movie nights, ex primal nights for any mount across the expansions; recently we've all taken to chilling out and shooting the breeze at a local tavern fc. That's not to say we're unhelpful for anyone outside of our statics: if anyone were to ask about high end content we have several experts in every role ready to lend a hand, and we have taught Savage fights to people so they could get a page and be prepared to go for chests in pf. It's just that raiding is not our focus as an fc: being a bunch of fun loving derps is.
If I had to pick something I liked most it's *that* I don't have to link my raiding career and non raiding social life together. When my group is done raiding and I'm looking to just chill out doing maps, watching movies, or playing other games, there are tons of people willing to do just that in my fc.
To go onto topic, I feel like I can only oppose this suggestion. I remember what it was like before xworld pf, especially during Midas: if you wanted to raid, you went where the pool of high skilled players was the highest. As a former Coeurlite, that was no fun. I don't think you can force communities in a way that wouldn't harm the way XIV's communities are set up now, and a lot of people do like and do benefit from how they're set up.
I do agree though I miss having to hang out at the raid entrance.
