Well, I don't know who's doing what. But I can say the FC I'm currently in and have been in since launch is pretty much a casual LS with like.. 1 current member that I know of that runs Coil with a static comprised of nobody else in the FC.
My FC has managed to save up about 2 mil for housing... that we're never going to get until the prices come down a by like 2/3 the current price, and this is speaking from a Non-Legacy server, which is in fact the same pricing as what the Legacy servers will be downgrading to over time. Still way too expensive for most FC's, specially my current one.
I've been thinking about leaving them for a while now but the leader is so rarely on that I never get a chance to talk with him. I want to at least talk to him a bit before I leave. The FC isn't going anywhere, and while there are some nice friendly people in it, there's no real progression. Myself and 2 others are probably the only 3 that are well geared and actually have a decent amount of gil to our names, and actually progress to some extent. I've donated probably 300-400k to this FC's housing pot, with the last donation a couple of months ago being like 200k. I kinda want that 200k back at least.
I have only attempted coil while running with a friend of mine and people he knows. So far non of the tries were successful, close, but just couldn't quite do it. I've tried Turn 2 and Turn 4, and my first horrific pug experience was in Turn 1 and turned me off to coil slightly due to the magnitude of dumb that radiated from that whole party. (the attempts later on, made me see that it wasn't as hard as I thought initially so I don't mind trying now.. just as long as it isn't a pug group)
Personally, I've almost got my Smn in a Full Myth setup. I don't really care about making everything BiS as long as it's comparatively good. My Blm I'm gearing up with CT, and my Whm I use to run Duty Roulette with ease. Needless to say those 3 are lvl 50, Relic'd and at minimum full Dark Light.
Slowly but surely working on leveling Monk and Dragoon to 50. Taking a bit longer because I'm doing both consecutively. Right now they're both lvl 33.
