Someone tell me the damage of Fox's dair please, or just look into Spacy shield pressure. People who say Wolf doesn't have good shield pressure dont know what they are talking about. Fox dair (I think, can't find individual hit percents to verify) does 2-3% depending on the hit with 9 frames of landing lag. Compare that to Wolf, who has 7 frames of landing lag and a landing hit! Here is why landing hits are important: First of all, being multihit + landing hit means you are protected with hitboxes the whole way up (rather then strong moves that you need to balance between hitting late to be safe on shield and hitting early to prevent an early counterattack). Not only that, but you always get the same safety. Landing hit on frame 1, equal hitlag, then stun on frames 2 and 3, then vulnerable frames 4-7, making it ALWAYS -4. Stale moves can't make the shield stun worse either, its at the bottom. I doubt Fox's is better then that. Look into the frame data of "good shield pressure" and you will see there is lots of holes. What makes Fox, Falco, Wolf, Lucario (know the least of his...), and Lucas great is they can do more then space/crossup shields. They have the flexibility (through shine/ohc/asc/magnet/djc) of covering most escape options. Requires prediction, but if you aren't into that you can always land, shine, Nair crossup and its still way more effective at dealing with shields then most.
tl;dr Look at the frame data for "good" shield pressure that works in melee, you will see wolf is very well off...
