I think that the sterotype that people who use items have no skill is bull. I use items and personally I think I'm pretty good, and I know I used to be good when I played a lot because I won a few local tournies (don't ask to play me, my internet doesn't play nice with brawl). I mean really, certain items like the bomb, smash balls, hammers and one hit kill items are cheap but I turn these off. Others like the bumper, sword and even the homerun bat can be easily dodged if you know what your doing and at the same time add an even deeper amount of strategy into the game, just picture this:
Player 1 is Falco with beam sword
Player 2 is a slow moving character
P1 trows sword slowly, P2 rolls to dodge, P1 uses the illusion (over B) and hits P2 up into the air, P1 then uses an upsmash to begin a combo.
Now if you can say that doesn't take skill theres something wrong with you.
