Why does my Brahma feel so weak

[(XBOX)EdgierDragoon3]

So I was doing a kuva lich mission and thought my Brahma felt weak, this is just on the enemy’s as the lich is resistant to blast, even so I use a mirage with her hall of mirrors augment and have a 480 eclipse bonus, did the Brahma get another nerf or am I missing something, any ideas would be appreciated ,   Edit so I’ve discovered that my brahmas aoe has greatly decreased from 18k down to 9k did the Brahma get nerfed again

As per usual, double-check you don't have any dragon keys equipped. 

It's a common enough mistake that it's worth doing.
