Well, I wouldn't have that much, but I still wish some more buffs would float our way. I don't think asking for something akin to Melee Marth would really be fun, nor would it even be fair, in my opinion. To emphasize my desire for buffs yet not an exaggeration, I'm going to ask for:
- Slightly more range on some moves (not all) many moves like bair, dair (spike not included) up smash, Shield Breaker; these all have great range already, so I find that just lesser things like grab range, down tilt, uair, these could use a slight more. A lot of people would disagree with me on this, but I feel as if his range is actually quite alright.
- Less landing lag on aerials. You're right, this is a major problem for me, whether I specifically combat it or not. While you could argue that having less endlag on aerials would make him perhaps a little too strong, I believe fair, dair, DB and down tilt could have less lag. Just some personal items on my wish list.
- Dair spike, my biggest and foremost wish. One frame of spiking hitbox isn't a lot to work with, making his dair generally unpractical and somewhat useless for it's original intention. Maybe a few more frames of spiking priorities, less lag, just a bundle of buffs could turn this move upside down. AKA, turn it into a good aerial, really.
- A follow-up throw. Down throw can be jumped out of, forward DI'd away. It's actually quite shocking to me that they didn't give Marth a completely reliable combo throw, and frankly, it just feels kind of silly. Down throw, yeah, maybe a different trajectory, maybe forward throw weaker, some little things I wouldn't mind.
That's really all I want, although I know for a fact that it's asking a lot. I know perhaps none of this will ever fully be granted, but every little step, I appreciate. I didn't however agree with everything you said, with the intent of making this game as balanced and versatile as it can possibly be (which is a completely different, complicated subject)
I think his tipper sweetspots are fine, minus down and up tilts. However, I don't see his hitboxes being worked on - it's not his sweetspot placement that makes Marth a somewhat mediocre character, I think. Nair has been buffed plenty, I think it stands as one of his best moves. Jab already links into grab, which makes it my personal most used move. Dancing Blade, while slow, is like it's Melee counterpart (at least more than Brawl) so, I'm satisfied. Shield Breaker is amazing, with great reach and potential. That said, I'm not a competitive player and have only ever been to one local, so it's most certainly not within any jurisdiction to say what's right, or what's wrong...
