Me, obviously crazy: Why limit infusing at all?

Keeps you from boosting amassing a stock pile during level up to then use only once you hit level cap. It encourages regular use.

Infusion Material Costs

• Infusion between two items of any rarity now requires only a single material to complete: Upgrade Modules
  
• Upgrade Modules can be obtained via the following sources:
  • Each of the Gunsmith Weekly Bounties award one Upgrade Module per week
    
  • Purchased from the Gunsmith for a rotating variety of currency and resources
    
  • Season of Undying free track Season Pass rank rewards
• Upgrade Modules are capped at 25 to limit hoarding, and to keep players unfamiliar with this system from sinking all their resources into a single item
  
• Discarding an Enhancement Core no longer deletes the entire stack

Definitely give us more feedback after you get some play time in. They are not limited by week. You will have 2 you can get from gunsmith weeklies, and you can get more from the season pass as well as purchase them from gunsmith for different materials. They also cost a little less to use than infusing previously did.
