I've got few suggestions that would make game a little more player friendly
1. Increasing max amount of potions from 15 to 50 ? or 100 ?
2. Show spots on minimap - if you can check them on web, it's just additional time to find them.
3. Lower quest items drop rate - Scroll of emperor and Broken Sword dropped after 2 mins of farming. Marlon quest items dropped from every mob.
