Bowser was my favorite character in Melee and my second best to use (Shiek was my best). Needless to say all these potential changes are making me happier. On the site, they said Bowser was going to perform differently than before, which I hope makes him a better character this time around. Granted, when I used him, he could stand up to the usual expert fox players at school, but he was still at a disadvantage due to attack lag and speed. Still, all I want is 4 things.
1) He keeps his attack priority or gets even more of it. One of Bowser's best traits was that he was a Mushroom Kingdom character. Mario, Luigi, Peach, and Bowser all had moves with a natural high priority, especially whirling fortress.
2) Keep Whirling fortress. It was one of the fastest moves to pull off in the game and served as both an offense with killing potential and a combo setup as well as a defense to run away fast with it. It also served in great edge-hogging.
3) Fire breath needs to be a bit stronger. It's good for shaving away life, but it didn't do so quickly enough and opponents would usually get away in time. Also, a little more flame time wouldn't hurt.
4. More reach. We saw he has more reach with at least one attack, but if all his physical attacks get more reach, it'll make him even better.
