It isn't. I use Link and I use shffl. That is pretty much it in terms of technical. That is all I need to use for Link. Of course I do other things but this is the only thing with Link that even takes practice. Everything else is really easy. Is that really so hard technically? Or how about Peach where you hold down and let go and it automatically cancels arials? Jigglypuff in general? Sheik and Marth are not hard technically either and they are arguably in the top three characters of Melee.
People saying that this needs to get less technical and we are all these technical freaks is silly. Only Fox, Falco, and Samus have hard technical stuff by any stretch of the imagination. I guess you can say it takes technical skill to do combos or whatever but isn't that character movesets which are so easy to perform?
Peach does have things that are pretty hard to do technically. You can think about her moves being easy, but when you put everything together it gets technical.
Dash dance -> Float canceled nair:
A little hard. Just dash dance, then Hold X, flick down and hit A. With no practice and trying to make it come out as fast as you can, you'll probably do dair instead of nair. With some practice, this isn't too hard.
Dash dance -> Float canceled nair: (but continue moving forward as you go into your float)
This is especially good against someone like Marth or anyone Peach has trouble against with prioriety. Often I use this to get under my opponent and hit them with a move that knocks them off the stage. The extra space covered from continuing to float forward, helps a lot. It can mean the difference between trading hits with Marth and knocking him off the stage and getting into an annoying fair combo.
This is much harder. Dash dance, Hold X, Flick the control stick into the down over corner, hit A. If you try to do this as fast as you can. Without practice, you'll end up doing a wide variety of things. Most of the time you'll probably do a fair instead of a nair. Sometimes you'll do a dair. Sometimes you won't move forward. Other times you jump nair. Sometimes even jump fair.
I think that learning to do this is much harder than waveshining. I picked up waveshining with Falco quite easily. It wasn't hard at all. But I still have trouble getting that nair to come out instantly and I've been able to do it that fast for quite a while now. I still have to warm up and sit there and practice it for about 20 or 30 seconds before I can do it consistantly.
If you want to do this as fast as you possibly can, I can guarantee that you'll mess up.

Ganon - Another character that has some pretty difficult technical things. Shorthop bair, double jump. Even harder is shorthop uair, double jump. I think you have to get everything down to the frame in order to double jump after a shorthop uair.

Ice Climbers - I don't even want to discuss out obsurdly technical these guys are. Try doing a desynch where one Popo does a wavesmash, then Nana does a wavesmash, then Popo a wavesmash, etc...
- Can anyone do the shorthop dair chaingrab, so that they can't DI out of it? What about doing a Popo dthrow, Nana fair spike, Popo dsmash. Climbers are obsurdly technical. They make Fox and Falco look like noob characters.

The only character I would say isn't technical is Shiek. With one exception. Her recovery takes a long time to master. I've been playing her for quite a while now as a secondary and I'm still picking up new recovery tricks. Just recently I figured out how to glitch on top of the corner of the stage so you lag less.
