A lot of people consider CC a huge deal when it comes to dealing with a lot of characters.
This isn't any different than Melee, and why things like speed and positioning of tools (maneuvering) is such a key factor in any meta-game, even top level play.
To think Lucas needs tool-adjustments to deal with CCing in a patch (3.0 or something) is borderline silly. It's GOOD that there's something people can attempt using as a counter measure to certain (or even much of) parts of Lucas in the Neutral game. He has such a solid Neutral that if there wasn't something to watch out for in the form of CCing, there would be an extensive lack of dynamics in vs Lucas matches.
He doesn't need tools, he needs you to play him accordingly in a way that works around this, uses this in the developing meta-game [Example: Baiting an opponent into trying to CC an approach and punishing them accordingly for trying to bait something from you] just like EVERY other character has to have something to work around (Lucas has to work around the opponents options as much as they have to work around his).
Play accordingly with what he has, no change is necessary.
Against everything that CC/Shield/other defensive/baiting/passive-aggressive measures would beat? Grab (or DD and punish accordingly with a Grab after they act when you don't take their bait). Against everything that would beat Grab like attacks/dodges/evading? F-Tilt (with its range/speed/etc this beats nearly everything, trading is fine too). Both can be done from any position in Neutral, passive-aggressive play, or when offensive or evading.
Don't worry about dealing with CC, you can literally nullify that as a factor in match-ups by playing accordingly. Not talking about the baiting game where it will always take a part (from your end vs their attempts as well), but in the sense that it's any form of 'advantage' against Lucas. It's silly to think so. It's a big deal, but only if you jump into **** by letting it happen.
