Exactly. And honestly, there really isn't much to pull from Wario Land aside from the ground pound and shoulder bash, the latter being his fsmash.
His bite, jab combo, forward throw and to a certain extent Corkscrew are all from Wario World. What more could you ask for, aside from the shoulder bash being a special? I don't really get this "not represented right" statement towards his design. The character has so much detail pulled from his games (his double jump animation is from his signature pose in Warioware Twisted, and when you charge his fsmash he charge up his legs like a should bash that isn't moving), and there was a lot of care went towards his animations.
I'm personally very happy with his Brawl design. He's very fun and true to his character.
