I am quite interested to see how this works out actually. Lighting Rod now (slightly) outclasses Volt Absorb. I guess it depends whether we want to keep the flavour ability or not. Offensive sets get a huge boost from this though.
Voodoom's ability will not change. The Gen IV CAPs will be transferred over to a PL server whenever Doug has the chance to do it, and they will be usable in random matches, but not a part of the main metagames in any way, shape, or form.
tennisace edit: I don't feel like posting so I approve this post. Gen 4 CAPs will not be updated in any way.
