It could be just that all my 3.5 experiences have been on wi-fi, but it feels unnecessarily hard to approach without fear as Lucas in 3.5. Fair is basically a noodle foot now; I'm about willing to bet it's harder to land the sweetspot on than Zelda's fair/bair, he still has a laggy projectile that gets telegraphed and punished too easily for how precise you have to be to land it, and magnet in general just seems to be increasingly often a bad idea the more I play him.
I did better in online matches with Bowser, Samus, and NESS (whom I pretty much didn't use until Smash 4) than Lucas tonight. I'm holding back too much judgement until I play legit people offline, but so far I just... I hate how finnicky he is at approaches in this build. I do like how skillful and precise he has to be now, but I feel like the changes went just a tad too far, and it's just not the same.
I realize we have DJC fair and it's really fast, but it's so tiny and flubby it just... makes it really hard to get used to. My Lucas approaches depend on fair and magnet doing their job, but they're really not. I can do mixups with nair, baiting the opponent out into a grab or PKF > whatever or dropdown dair, things like that, but it feels really hit-and-miss. Nothing feels like a solid "marth fair" approach or anywhere near it. For what it does, fair currently doesn't feel worth the risk. It's supposed to be his best approaching aerial, but it's still pretty bad. Before people jump in on me, DJCability doesn't make it godlike. It still has startup, endlag, and movement limitations. Not that Lucas is bad at movement, but... so far, I don't feel like his mobility makes up for just how terrible f-air is.
Also as a side note: for me, it's hard to tell when nair is going to launch forward or backward in the heat of battle, which hitbubbles decided to connect. If I could, I'd honestly change the trajectory all to one direction or another so that it's consistent. I can always react but I hate that my followups are occasionally interrupted because I misjudged where the last hitbubble of a superfast move connected on a random extremity on my opponent, and my punish is basically thrown out the window. But that's a random tangent.
Point is that, in general, I feel like 3.5 Lucas has Ness' 3.02 (idk about 3.5) problem of having a crappy approach. Pretty much the only thing he seems good at is solid punish combos and hard read punishes with massive damage, ala OU Usmash. A little DJC pressure in there, but it's nothing anyone who's used to fighting Fox or Falco can't handle. Lucas can't even magnet very well anymore because, ayyy 4 more frames of hitlag for some reason so I can get shined out of pressure. Oh, and shield DI TOTALLY isn't a thing in this build.
Again, it could be wifi messing with me, but I'm also getting the impression that there's a severe lack of any reliable combos with this character now. Like, Samus seems fine, Bowser seems fine, Wolf seems fine (naming characters I've used), etc. I was never one to abuse dair > anything, so that nerf isn't a problem... It just feels like he was designed one way, worked one way, and then half of him was suddenly changed and that half of him is out the window. I'm sure some of this feeling has to do with me not being used to the new moves, especially considering how often I used wavebounce magnet mobility shenanigans to get my combos in 3.02, and now Lucas' wavebounce range got shortened. However, it's starting to feel like the only Lucas players who weren't completely destroyed by this patch A) never used magnet, shield pressure, wavebounce, or fair at all and B) played him "like Ness" (is the best way I can describe it), aka running along the ground in a linear fashion, using boring crap like his fsmash as a common kill option, abusing his comboability into OU upsmash, and didn't utilize his mobility at all, when it was central to so many of his amazing flashy mixups that weren't even OP, just honest, flashy, and solid reads/combos that didn't do a billion % damage.
I know people are gonna want to jump on my ass for even remotely judging based on wi-fi matches, but I promise I'm not making a full assessment. More like, plotting trends of things and giving my opinion on how it MIGHT work out in an offline environment. I also know some people are going to be like "ha-ha, your character sux 3.5 sux don't you feel like an ass for liking 3.5 before!!!!1" but I'm gonna say that I still like 3.5 as a whole, just... Lucas has problems and, while probably viable, is being taken in an unnecessary and boring direction with just a few poor decisions on his 3.5 design, and I may just drop the character and go play a freaking Melee character like everyone else who runs this game's development and wins all the money.
tl;dr, how do approach with 3.5 Lucas in any MU (that's not jigglypuff) and not get punished?
