Glad you're back. Invite sent.
I routinely kick people for inactivity to keep the clan healthy, and we're always happy to invite people back when they pick the game back up. It's nothing personal. For the sake of transparency, the clan doesn't have a firm policy for inactivity, but I usually let people who are under mastery rank 10 go for no more than 20 days or so offline. Higher mastery ranks get a little more flexibility, and I've created a special rank for people who are on a break and let me know.
If we wait for extended periods to see whether new players are going to be consistently active, it could hurt us during clan events and ultimately kill the clan entirely as our active players could seek out more active clans. I think brininging people back in as they request is a better approach, because at least we're inviting the folks who do come back to a healthy clan. Also, every clan member has the permissions to send clan invites, so it shouldn't take long.
Anyway, welcome back!
I've been a little bit scarce while dropping a platinum trophy on Horizon Zero Dawn, but I've still logged in every day. Fantastic game BTW.
