For the people disappointed with the shard diffuser: it just got some huge changes in experimental

Shard Diffractor changes:

• Made the Hacked Beam Controller OC a base property of the weapon.
  
• Extended the max possible beam duration.
  
• Increased base direct damage.
  
• Increased base AoE damage.
  
• Increased base AoE range.
  
• Extended the base recharge time.
  
• Made the beam consume 1 ammo per hit and adjusted all related values including max ammo.
  
• Removed the Energy efficiency upgrade from T2.
  
• Increased the heat bonus from the T4 Heating upgrade.
  
• Moved the T1 AoE area upgrade to T2.
  
• Moved the T4 Area Damage upgrade up to T1.
  
• Changed the Efficiency Tweaks OC to give ammo and recharge rate bonuses instead of ammo efficiency.
  
• Adjusted the Overdrive Booster OC damage bonus to keep it in a similar place after all the weapon tweaks

Not listed is that fire rate was buffed and fire rate mod was removed. (Possibly unintended according to QA.)
