Aegis storm feels much better with the rework for better mobility and finally being able to cast abilities while it is active. It's a little unfortunate that the Alt-Fire augment for Balefire does require the player to be using Aegis Storm, because it does feel significantly better to use than the charge fire mode. I do wish that it was possible to use other weapons than balefire while Aegis Storm is active, and being able to aim down sights to try to get Hildryn a little more out of the way when you're trying to aim.
Balefire did get some buffs too recently like staggering enemies instead of ragdolling them, and charged shots consuming less shield and a slight increase in damage.
It's not under NDA anymore, so you can check out streams or what people have uploaded to youtube if you don't mind spoilers. It is in pre-alpha though so things are likely to change between now and whenever it releases.
