I'll try and do my typical "yeah, she has negatives, but she has positives" comparison on Puff...
- Low range? Well, yeah. Low range.
- Some moves are low priority, but most of them are just so slow it seems like they have terrible priority because lots of other hitboxes come out before them.
- She is indeed the lightest character, ans though it can help in some situations like not getting combo'd as much, you could argue that a character doing half a a bread and butter combo could put her in KO range because she's so light.
- To be fair, Rest is decent. It's not terrible, but it's just not something you fear anymore, as it cant take your stock from a single mistake. It deals incredible damage, but it's main boon is for killing, and even though it still kills rather early relative to a lot of kill moves, it's still not as rewarding as one would expect for such a laggy, punishable move.
- No combos is kinda true. She can string aerials together pretty well, and has a really good off stage gimp game. It would be fantastic if she had a reliable way to get an opponent in a scary off stage position easily, but she doesn't.
- She is VERY slow, but is very fast in the air. You just have to play it right I suppose.
- I'll just add that though the shield changes may have helped her Pound and Back Air and Smash Attacks loads, the fact that she dies off a shield break makes this irrelevant, especially when you have characters like Marth. Lucina, Samus, Yoshi, Bowser, Ganon etc who can all destroy a full shield instantly.
Meh, even some of those I had to scrape the bottom of the barrel for. I don't like this whole *reels off only negatives* fashion. Every character has some positive, no matter how little it is. That's Jigglypuff's problem; her positives are so little, she just doesn't have much of a chance to shine. It's such a shame, because a better launch angle and more power on Rest could totally make her main gimmick scary.
