Chain Lightning II seems to require 4 targets to be able to function, rather than *up to* 4 targets. This seems to be a nerf when Chain Lightning can be used with 2 targets. I had 2 swamp dragons next to each other that I needed to use Chain Lightning on but couldn't because there were no other targets nearby. I even used it on an allied unit just so I could get the 4 targets at one point!

Can Chain Lightning II be made to be usable on 2-4 targets, rather than only 4, please? If this is already achievable, can someone please tell me how? Cheers.

One thing you can do with all chain lightning skills is target empty tiles. This way you can also extend your range by just hopping on a empty tile and continuing from there.
And it seems you did manage to shine light on a bug. The range where you click should always follow the last click.
