A ley line champion (Discussion!)

Short post, but I think a champion based around a ley line passive would be pretty neat.

I happened upon this while thinking about a plant champion that would root themselves in order to draw health (nutrients) from the soil but thought that with zyra and maokai, the plant thing would be rather unoriginal.

So I stepped up and said 'what about a mage tapping into the ground?' Through ley lines/wells of power.

I think there's a large potential for a champion based on ley lines, but it certainly has its' problems.

• If the ley lines are visible on the map then it's easy enough to avoid his power.

• If the ley lines are NOT visible on the map then it's very easy to unknowingly walk into one and get obliterated. (which is a neat thing for the ley walker to play around, but it's unclear for his opponents)

• Making a dynamic passive the core of the ley walkers kit may unwittingly subject him to games where RNG makes him next to useless, as such his kit would have to be able to cope even without the ley lines, but then the passive may feel underwhelming. Balancing the feeling of power on the ley lines without making him broken with them/useless without them could prove difficult.

That's all I can think of off the top of my head, PLEASE suggest your own ideas/possible problems in the comments below as I'd love to really flush out the concept. Thanks!
