If people are drifting away, Fsmash should be always a good atack to punish landing foes, al though the timing can be tricky, since Ishley said theres only about 3-4 frames of vunerability.
I thought utilt was a garbage move, after i saw the grounded vs air hitboxes, then it became really awesome, and its kinda "instant" compared to usmash
Dair i just dunno why im using it too much, most of the time I get away with a trade or I just get away with it and its a whooping 15%.
Im not still convinced on the Ftilt though, its not so good, and on shield its terrible, may work for mix ups but still nto a move Id rely much on.
