My last idea you guys can try i wanted to add it to my idea of the gaining some boost from the second jump using magnet. Give magnet a push effective. Fox's shine pushes ppl away from him, but also gives damage.. Don't allow damage, just allow magnet on start up to push opponents away at a set distance. Basically, lucas is pretty stable, but you guys aren't treating lucas and ness like how u treat fox and falco.
I'll explain, Fox and Falco have similar moves, but different play styles, falco shine forces opponents in the sky, fox pushes them away. What i am saying is instead of making ness feel completely different from lucas allow him to remain the same and still have a slightly different style. Lucas magnet combined with his PK fire/freeze gives him a horizontal boost, Allow ness magnet on second jump to give him a vertical one. Lucas Ending frames on Magnet pushes opponents to the ground. Allow Ness's startup on magnet to push them away, with no damage. Atleast i feel if ness is getting shield pressured, he has a better chance to escape it with that move.
Ohh and last but not less, allow PK thunder push the opponents slightly downward instead of upward. Like how sonic's spring kinda of messes with your recovery, similar to that. It's just ideas i am throwing out there. I would think you guys try most of the ideas you see in the thread with the playtesters and i would like to know if mine comes off as overpowered or not to effective.
