Thank you guys for the support.
Something fast about my match against Dabuz, I know, in paper, how the matchup goes, the part that threw me off is that Luma's jabs are just too strong that most of G&W hits either break at Luma's jabs or just cancel each other (which is why I had a hard time taking care of Luma).
Another thing, I hope this shows you guys that in this game, if you want to be a great player with your character of choice, you CAN do it, of course, Sheik or Rosa will still be better characters but the others are not that behind to be seen as "useless".
