She can't use dash when flying, making the custom animation pointless and wonky.
Her 2 not working together with her 4 is also unintuitive, since pillage is vital to the kit, everything about the rather long landing, pressing 2 and waiting for 2 secs so I can maybe fly again is just bad. It isn't like aegis storm is doing much, since slowly killing things doesn't breaks the already broken power scale and the ability will be mostly used for its CC.
2 does not work against infested, I thought the lesson was learned with mag's polarize about skills that become immediately useless against a faction, even more one as vital as shield pillage.
4 is not fun, the damage it too low and being locked out of all weapons that aren't her 1 makes it press and forget to cc, since balefire is a raw weapon aka=not usable at all when it matters.
And yeah, balefire is a raw weapon with low fire rate, feels like a nerfed sonicor. On a frame that drops from the "endgame" boss.
