How you choose to spend your boss skill points in PoE 2 can greatly depend on what your preferred playstyle is and the kinds of maps you run. Some nodes have more clear advantages than others which can be conditional and need careful consideration. 

First Set of Points:

• Option 1: 15% increased quantity of items dropped by map bosses.
• Option 2: 25% increased rarity of items dropped by map bosses.
• Recommendation: Go for quantity if your gear already boosts rarity.

Second Set of Points:

Radiant Waystones: Increases the quantity of waystones dropped by bosses by 10%.

Note: Currently, waystone sustain isn't a major issue, so consider revisiting this choice.

Third Set of Points:

Choose one of the following to add to all boss maps:

• An essence
  
• A shrine
  
• An Asmary spirit
  
• A strong box
  

Recommendation: Opt for an extra shrine or essence, as strong boxes and Asmary spirits are less beneficial unless buffed in future updates.

Final Points:

• Organized Forces: Increases area level but may be redundant if using precursor tablets.
• Corruption Node: Offers a 30% chance for boss maps to contain corruption, adding monster density and rewards.
• Recommendation: Focus on increasing rarity and securing an extra essence/spirit for consistent rewards.

Appropriate spending of boss skill points goes a long way in improving your PoE 2 gameplay experience. If you focus on boosting item quantity and rarity alongside selected nodes to your playstyle, the overall experience improves. And as always, be flexible; change your strategy as the game progresses.
