Add mystical weapons, which regain 1-2% of damage done to your HP. For example a Dagger that hits 8 Damage and regens 1% will give you 0,08 HP back.
I got this Idea from the Zodiac Server on PC.
iEra currently has the Legend of Era sword (the golden sword) that allows the user to heal himself. Despite the infinite usage, it heals too slowly which makes it nearly useless. The freeze rate makes you very vulnerable. Since players have a large supply of food/healing items, the healing ability is rarely used.
There should be a bigger gang base like you can pull up in your car and crash through the loading dock where the drugs are being put in trucks (little job for controller of base) ideas!
