I am a bit confused. I read through the patch notes multiple times and no where in there does it say anything about a decrease in super energy granted. HOWEVER, it DOES state that base super energy has been INCREASED from all tethers to provide a more consistent and less exponential experience. Also stating that more super energy will be granted for tethering more powerful enemies. Yet when I play the game, places where I used to be able to tether and get my super back only give me 60 - 70% of my super back rather than an instant recharge. This is definitely a DECREASE in base energy granted, not the INCREASE that the patch notes specify. Definitely a much less consistent result too, also contrary to what the patch notes specify.
You are missing another part of the patch notes that you overlooked that explains your issue.
No longer grants Super energy on bloom and damage sharing[/quote]
That is why you are receiving less super energy.
