At this point, with 2.1 being only a few weeks out, I think the lockout system needs to be dropped honestly or at the very least, reworked to allow a couple or few runs per week (perhaps 2 or 3 Job lockouts, not a single character lockouts)

There are a few reasons for why I think this.
1) People need to clear turn 5 before 2.3 comes out else too many people will get stuck in "old content" that is basically a ghost town finding less and less people to be able to make attempts with (try to get a story 8 man together or even chimera at even this point)
2) In that time with the Myth cap being at 450, everyone is going to have full i90 without much of any trouble anyways.
3) as included above, if people want to funnel gear to one Job, so be it, they have to do it for 9 other jobs still and will most likely want to play more to get to that point (thus being more active and the servers continue to be lively)
4) We have access to 9 different jobs, but can only really play one of them per week.. <-- bad design IMO
5) If people want to pay to be carried? Then honestly, so what? If that makes them happy and finds the game fun still, isn't that the point of a game?
6) I believe far more people then most expect would use this as a tool to help fill spots of missing groups, not just carry people through the content.

I'm ok with the lockout being the way it is for the current patch and going forward for each "progression" patch, but this single character lockout during the off "vanity" patches is going to get boring very quickly and I think that far more people will get bored well before 2.2 comes out.
