It appears some mobs are now so close together you are unable to attack. I was farming Biets around Kitty hill in Elysium. All the Biets are now in 2 packs comprising 5 or 6 critters. Impossible to attack without a whole platoon behind you for support. What's up with that? Some Composite Nano are messed up also. I now have a Composite Utility with the Health and Nano buffs as well as the Composite Medical with the Health and Nano buffs. The two Nano lines are mutually exclusive. The Composite Utility should have also included the HP and NP Regeneration Or better yet, The Composite Utility should have the HP and NP buffs removed so I can still use both Nano on myself and my pets.
