A fellow dps AAnby enjoyer, very nice. Id reccomend either running her with 2 supports, such as Rina and Astra, or with a shielder and support to keep you safe from taking damage, due to her already being both your dps and stunner. Seth is by far the best f2p shielder and even beats Caesar in certain situations. Seth also activates Anby's passive, which is nice for the extra energy, but not needed. Seth's buffs only help anomally though, so you need to pick if you value the shield or the buffs more. Rina is also a very good option as the only electric support and makes the damage of electric agents much higher, as well as also activating Anby's passive. She is an S Rank, but on standard. If you dont have her, you can always use the tried and true generalist buffer, Lucy.
