Also, jiggs has an amazing airspeed, good aerials outside of the range problem...Good tools for retreating, and a decent recovery if mastered.
That combo is decent, however as shown in that video (and I have done some testing with this combo), you still need to be extremely close (as in touching your opponent or almost touching your opponent) for the combo to work and if you miss it...... yeah. It is however a decent set up that is able to give you the opprotunity to land the rest with a slightly lesser chance of missing it and a lesser chance of putting you in a super punishing scenario.
Also, good air speed and decent aerials with poor range won't help when you have very poor ground options. Even characters like
have anti-air options when it comes to
by spamming U-tilt which covers so much room and comes out very fast making it almost impossible for her to approach in the air and if she does manage to land a hit,
and
end up trading. But I agree that she has a pretty good recovery that can sometimes be hard to keep track of but even then, that won't do you too much good if you are able to be KO'd by non-charged Fsmash's extremely early because of your weight.
