Alibi doesn't work all that much, her gadget can be easily countered. Ela is a good roamer and her concussion mines are helpful against a variety of Ops. Nomad isn't all that great, her air jab can be countered decently easily. Kaid is basically a better Bandit. You just need to adjust to the recoil and the gadget's uses ever since the 1.4 meter reach buff.
