in the long run, it'll help teach u to play while making less mistakes, or losing that neutral position which is very critical and should be worth worrying about. Since combos in brawl are somewhat lacking, it seems you can get away with doing risking stuff more often, and have less regard for your health/percent because since combos are short, punishes arent as severe as other other fighters.
In addition, smash has that combo breaker factor that comes with DI. Having good DI will get you out of a string load of what should be combos, so it seems that even more incentive to play without fear of your health. Now in the long run, if you win more neutral positions that u loss, u should come out on top in those traditional fighters, but smash is kinda different. Since a stock can come around at any point regardless on percent as long as ur off stage, capitalizing on stuff like meteor strike and edge hog opportunities are more critical. Now if u play games with same sense of danger that comes with 0 to death combo at any time regardless on what game or character, it could make u a better player and could help u to transition to another game.
Or it could lead u to become a campier more defensive player. Just my thought....
