Wavedashing isn't all that important. It's good, and at higher level play you should know how and when to use it, but as far as tech goes, I think wave
landing, dash dancing and shffling are much more practical skills to learn. Mindgames are huge, but they don't require tech (although tech can be a useful tool in mindgaming an opponent).
Idk much about Lucario, and most of this is coming from a Melee background, but the only characters I've seen who really scoot around with wavedashing are ICs and the Mario Bros (mainly Luigi). Mostly wavedashing is for quick spacing. Someone correct me if I'm wrong here. My experience in Melee isn't anything to sneeze at, but admittedly its much more catered to the Links and the Plumbers.
You should practice it. It took me maybe 10 minutes to get down when I first learned it, it was learning
when to use it that took a while.
Gotta admit though, when I read the title "I have no desire to wave-dash" I did automatically think "Oh... One of those guys."
You should learn it, and just keep it in your pocket for a rainy day if you really don't want to use it.
I do it by short hopping with
![Gamecube X :GCX: :GCX:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
then air dodging with
![Gamecube Left Trigger :GCLT: :GCLT:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
(some people use
![Gamecube Y :GCY: :GCY:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
and/or
![Gamecube Right Trigger :GCRT: :GCRT:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
but it feels weird to me) then hitting
![Gamecube Joystick Down-Left :GCDL: :GCDL:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
or
Keep doing that, faster and faster until your awkward triangular jump becomes a slide. It's pretty simple. Again, no one's forcing you to learn it if you don't want to, but there it is.
