Town Portals That Dont Close

Hello friends (& rivals to be),

Do you find yourself progressing through an area and filling you inventory with new loot that will improve your build ?
Do you enjoy going to town and looking at the item closely and comparing it to skills on your skill tree to see if you can find some synergies?
Maybe you're even the sort who invents their own builds?

If so, then you've probably noticed, that by the time you've taken a few extra minutes to look at your characters items and build, and consider creative alternatives that your portal has closed and you'll need to start that area over.

In all seriousness though - can anyone tell me a single good reason that town portals close while you're in town ? I honestly don't remember that being a thing in POE1 or any other game that uses a similar system.

Thank you for your time,

I believe it was a thing in POE1 because instances were never saved or there was no pausing etc. But that has since been fixed in POE2 so it feels like a vestigial system left over from POE1 that has yet to be fixed.

Hmm, still, quite an odd mechanic IMO.
