The issue with that is, over the last few years, the userbase has made it abundantly clear that any form of limited connectivity DRM beyond the VERY FIRST TIME YOU LAUNCH THE GAME for offline mode is unacceptable.
EHG has previously considered a once every 30-day DRM check for offline mode, which would function in a way to allow cosmetic unlocks in offline mode, but due to previous promises and claims during their kickstarter, alpha, and beta, they decided against that since the users were promised true offline mode, which entails everything they’ve given now.
Having no check on cosmetics for offline mode would just cause people not to buy cosmetics and play offline mode with mods and file modifications. It would hurt their profit-margin.
Having temporary checks for cosmetics would go against their original promise and the second promise they made after mulling it over on the forums and Discord.
Offline mode will have one check when you connect to the game for the first time on your computer. Afterwards, so long as your computer is the same, it will remain truly offline. This allows you to use mods and skin edits on your personal machine to do all sorts of things in the future, which means offline mode in the potential future could even have a modding scene like Grim Dawn.
This has been discussed in the past, long before you joined. The users who supported their kickstarter and alpha/beta came to this conclusion after much discussion on this forum, and I’m sure the threads are still around somewhere.
