With my time spent in eureka recently(and the brief time in Bozja, getting all my weapons to recollection)
I noticed how With eureka zones[and maybe Bozja, despite not spending alot of time there.]
How With the time you spend preparing, and setting things up. You will always face against the Timer, a Lock of the Duty Zone, or your own timer keeping you there for a limited time, til the moment you may not end up in the same zone with those before.

Thus I feel it'll be a QoL if SE ads new exploration zones in the future. if they add the options(as follows)

*A way to increase Personal Timers.[or a npc that allows you to increase your timer with certain amounts. while understandable for multiple reasons. it's also understandable when a player has reasons to increase said time.] and hopefully, implemented in a way that doesn't make it a false game, or requirement to craft or create or farm for the extension. Since some players simply want to not worry about getting booted for being in the zone for awhile when enjoying their time with others.

*A Manual Way to Lock, or Unlock Zones. I have seen this alot<in my brief compared to others> in eureka zones. [haven't been on Bozja enough to tell if it even is a thing in those zones] It'd make it so if a Collected group wished to join on their own, or a FC. they can do so at their leisure. as well as make sure that zones that can grow do not face being clipped early.(while understandable that it is a thing for technical reasons or load at times to trim the excess. it also can become a feature, than a hindrance.)

*A Fixed timer, that gives a Example of how old a zone/session/duty is. be it on the duty info, or even in the timers under duty category for use within content. this used in context with other information depending on said content will offer players more choices.[even the option to decide to back out if, in eureka case. if things will take a while to appear. a player with limited time will leave beforehand. whilst a player with time can prepare themselves before setting off into the content.

much more can be said and done.
and I'm sure I ain't the first to mention something related to this.

[Just a post to get an idea through, if others have similar ideas, or ways to possibly put it all together, feel free to speculate. I am unlikely to reply, since it's only to put an idea out.]
