Much better, I like how you take constructive criticism with stride. I would suggest adding a little more to Lucy's personality so I get a better idea of what she is like. Also her alchemic specialty is one I cannot allow. For one, any weapon will not be able to withstand alchemic channeling. Also there is no such Alchemy out there that can disrupt or cancel alchemy. The only thing capable of that is the anti alchemic ammunition, once the substance enters a person's blood stream it make it incredibly difficult to cast alchemy. Other than that a few Chrono Asylums are able to disrupt alchemy, this is done by causing an influx in the alchemic pressure in the surroundings hence making casting difficult. 

Here is a list of Alchemic specialities you can use,

Poison Generation

Earth Manipulation

Fire Manipulation

Lightning Manipulation

Empathy

Acid conversion
