Tech skill is for *****es (not really though).
Dtilt combos into itself (kinda like Zelda's dtilt in Brawl) and Melee players aren't used to that so sometimes they don't DI away and I laugh as I get dtilt x7 > jab reset > fsmash.
DJC PKF is overrated. Only time it's clearly better than PKF sometime during a regular SH is when dropping through a platform imo.
EDIT: From the recently-released change list:
[collapse=Lucas]-Lucas' Cliff Jump height slightly reduced
-Lucas' Air Jump animations cleaned up
-Lucas' Boost Smash window adjusted to be more appropriate for his jump speed
-Lucas' Forward Smash angled up does slightly more damage while angled down does slightly less
-Lucas' Down Smash is two parts just like Link's Forward Smash
-Lucas' Neutral Air now uses weight dependent set knockback on linking hits and is slightly more SDIable
-Lucas' Forward Air has normal hitlag
-Lucas' Back Air now uses the new Light element effect
-Lucas' Up Air has normal hitlag, and now has a sweetspot that uses the new Light element effect
-Lucas' Grab animations edited to not look as awkward
-Lucas' Tether no longer has a hitbox attached to it when it is grabbing the ledge
-Lucas' PK Thunder no longer dies when entering the side blastzones, and does not clip stages as easily
-Lucas' PK Thunder no longer dies when Lucas is hit, and instead becomes unfriendly towards any player and continuing in the same direction before he got hit
-Lucas' PKT2 ending is not as short and is able to grab the edge backwards
-Lucas' PK Freeze has less hitlag and is now SDIable
-Lucas' Down B has an actual start up animation, allowing reversals, but the hit and jump cancel timings remain the same as before[/collapse]
Nothing on bair being faster.
