Lucas wass often compared to Ness, but it was a mistake. Yes, Lucas did have many of the same problems as Ness, but he also had a host of problems on top of that. Lucas needed serious help.
What Lucas got was not only a solution to the horrible problem of grab release, but he also saw his bread and butter moves refined to be on the same level of power as the better characters. Lucas is still focusing on setting up tricks with down aerial, getting reliable damage with jabs and tilts, and poking with Pk Fire. He just gets a lot more reward now when he does that.
Overall, Lucas plays the same way he always did, but the big change is that now his playstyle is much more likely to result in him winning.
