I sure hope HW is not going to be more armor grind treadmill!

I've been telling people man... Dynamis, and some sky or limbus type place, with great gear grinds, that whole free companies can go to once every 2 or 3 days would be a game changer, and give us a reason to communicate and chill with our free company. Legendary cursed artifact gear or something.

Pretty sure that's what FC airship content will do, but Dynamis content is a consequence of game limitations, not an active design choice.
See, back then games didn't instance their raids. This caused MAJOR problems.
In fact it still does in XI, just on a slightly smaller scale since Dynamis is soloable now, and they just recently got rid of entry limitations.
Add to that, I've looked at those dynamis grinds. The MONTHS required to get anything meaningful are horrid.
We already have raid content you can do with your FC, it's just on a smaller scale so as to not discriminate against those with smaller groups, and said content is getting its systems adjusted in Heavensward to promote getting more "butts in the seat" so to speak. Not every FC has over 100 members and should not be actively punished for not pursuing that number.
Which creates the question of what exactly constitutes "whole free companies."

Not always. All my friends (and I know a lot of people heh :/) who left, never came back. My FC has more "MIA" then active players..and these people are def not subbed. Still unacceptable to say imho! You never want people to take a break from a game like that, because there is a good chance they won't ever come back.

I'd be more worried if people DIDN'T leave. That's the nature of MMOs. Many, MANY people are just going to leave after a while. It was true in Ultima Online, it was true in EverQuest, it was true in WoW, and it's true in this game.
The fact that people that cite worry about this still manage to maintain FC numbers over 100 should offer you insight into how this type of community works.
