Pottable badges were restricted due to orders from KMS not wanting us to have better badges than the KMS meta. Why go for the Black Mage badge when we have Ghost Ship Exorcist, and all that. I agree that it was a poorly thought out decision, but honestly the only way I see them returning is if KMS makes them the new meta.
Nexon needs to start realizing that different geographic areas have different playstyles and needs to stop seeing whats better or not in terms of gameplay but in terms of their playerbase.
So this would only apply to harvesting where 100% kb res would help us not get knocked too far to harvest and have to redo the captcha over and over. As for invincibility it would only apply to maps with anti afk mobs, again only when harvesting.
