I'm not really clear on what's happening there, is this an attack people can dodge?
I don't understand this, either. If it was already implemented, then why were they Subsonic? Also, to be fair, dodging a normal thunderstorm probably wouldn't net MHS, since you'd only need to move a meter or so compared to thousands of meters moved by the storm. The crux of this issue is arguing that Electro attacks are 1:1 with real world lightning enough that we can consider them to be the same speed, rather than the speed of other sources of electricity (which we can rate as low as Subsonic, in fact).
