Yes, the game mechanics are set up nicely, relying on timing, rather than insane combos. That's why I play Cassandra (sp?) in Soul Caliber 2. She's almost completely based on timing her attacks to hit the enemy at the right time.
In any case, I prefer to play Marth in Smash, because of his character mechanics. He's agile, and jumps well. He's not too light, so he doesn't fly like Jigglypuff, and he can deliver some massive hits. He's kinda slow at times, (There's a bit of delay when he begins an attack, and fast characters can take advantage of that) but he's well suited for my style of gameplay. I tend to keep doing small attacks and trying to avoid direct confrontations. I like to slowly do damage by hitting them in air, and I spend most of my time jumping around, or R dodging.
I don't know what you're talking about, wave dashing being taken out? It was left in the game by developers because it improved gameplay for the higher skilled players who could pull it off.
