I'd be happy to help you analyze the text about Destiny 2's Vanguard season 4!

Here are some key points I extracted:

1. Added a new 5-piece Vanguard armor set as orange rarity rewards from the Armor Cache.

2. The armor cache prices increased by 80 million within 5 minutes of the announcement.

3. A Vanguard set has been spotted in the item market.

4. Season 2 will introduce four new weapons: KG M40 Assault Rifle, Whitley LMG, Armaguerra 43 SMG, and Ice Axe.

5. Previous season's Vanguard sets, armor, and shaders are still available.

6. The expansion is called Curse of Osiris (Season 1).

7. The new Armor Synthesis system has four stages.

8. Social space became the new base for Vanguard operations at the beginning of the last season.

From your own experiences, you mentioned:

1. You play about 4 days a week and complete weekly bounties, strikes, etc., but never drop the robes on your Warlock, even after playing other classes for 3 weeks.

2. You've gotten full sets of armor on other classes (Hunter) within 2 weeks.

As for guesses on bonus, armor rating, or where it slots with other oranges, I can only speculate based on the information provided:

* Bonus: Possibly increased damage output, health regeneration, or reduced damage taken.

* Armor Rating: Could be a balance between high defense and moderate mobility, considering it's an orange rarity set.

* Slotting with other oranges: As new content is added, the Vanguard sets may receive rebalancing to fit into the existing armor hierarchy.

Keep in mind that these are just hypothetical suggestions, and actual game mechanics might differ. If you have any specific questions or concerns about your Warlock's armor drops, I'd be happy to help!
