List of things the game needs:
1. Add the Ready and Dodge Action
2. Add all the Classes and Sub-classes from PHB
3. Add all the top 10% requested Classes and Sub-classes from the other Official Content sources (Ex. UA is not official content. Xanathar's Guide is.)
4. Add the Multi-class option.
5. Tone down the Status effects a bit.
6. More common and Uncommon items form DMG.
7. Capture, questioning, and torture of prisoners.
8. Allow for custom backgrounds.
9. More Companion Options.
10. More +1 types of gears Shields etc.
11. Adding custom gears from Larian's brain.
12. Adding Rare and Very Rare Items from DMG
13. Ability to make enemies eat their young.
I disagree about the arrows. Because it is a PC game and making me pick them up would just be too painstaking.
