I kind of agree with the thought that at high levels, playing against ICs is basically a set long execution test. Just like every other aspect of the game, ICs players have optimized wobble setups so "just don't get grabbed" gets harder as time goes on. Miss a SDI on a neutral exchange, you're down a stock. But I think that's relatively minor, the bigger problem with wobbling is at the lower and mid levels where the neutral is either non-existent or not as well developed. That and it's bad for viewership, and viewership is important because sponsors aren't going to fund tournaments without viewers.
Apart from limiting wobbling to 100% instead of 300%, my solution would probably be to limit it to once per stock. Not 4 per game, if ICs lose a stock without a wobble that opportunity is just missed. I think that would make ICs sets a bit less volatile while still giving them their primarily kill option on floaties.
The real craziness to me is all that talk about rule changes intended to nerf Puff. I think camping rules could probably be tightened up if there was some way to properly enforce it, but aside from that character specific rules and limitations are kind of ridiculous. A ledge grab limit isn't a bad solution, since it's universal and wouldn't impact 99% of games since they don't go to time. It's not a complete solution either though.
