I feel the middle one is outclassed by ak's and other denials. They dont have such a big lock but they have more punch(you are trusting in only 3 cards, the fractals, to do everything in the deck, chances are you will have problems with the offencive once your denial is up) and pack discords and CC as asistance(they can disrupt the enemy faster, and kill what they manage play).
I feel immo rush with 3 immos= too unreliable for solid winning and not that much fast(i bet a rainbow rush can beat it in speed and consistency).
And the last one, well, it looks like a fine control bow, although those hourglasses might be too much(and the quanta might need some tuning).
