Does this help easily remove difficult to remove solder from pcb pad/joint?

Yes, although liquid flux might be easier. Generally I add flux, heat the bad joint and then flow new solder into it. Then I simply reheat the joint again and remove the solder as normal. Hope that helps!

Can you use this for soldering on pcbs such as xbox controllers?

Yes, flux helps the solder flow and reduces oxidisation

Is this water soluble flux?

the manufacturers website says it's not.

Can this be used for soldering copper pies

I would say NO. In my engineering days, we used a flux powder mixed with water and painted it onto the copper based metal to be soldered. I think now they use a silver type solder, no lead. This flux is used on soldering wires.
