I pretty much agree with this. I've already posted on most topics as much as I'd feel like and dont feel like posting much more. Maybe in the stage discussion thread if its on a stage I play on. But I dont wanna theorycraft and put in data for something that might not be true.
The theorycrafting people should be doing are options that are actually viable. This typically is harder to assess though. I mean, I feel like Snake should be played certain ways against various characters, but others will argue you should always camp. Grenades I feel are of limited use against some characters like diddy kong or fox.
Bananas and grenades to watch out for make you spent more time avoiding conflict than attacking. It's probably better to take Diddy and Fox head on with grenades and C4 only when they should be used. Like in edgeguarding or recovering.
Against fox I feel it can be taken a few ways. The typical shield-drop -> throw is stupid. Blaster spam will eat the grenades and explode in front of you, or reflector will reflect the nades. If you attempt to camp fox I really think you should jump and toss grenades like that. But really, only camp fox if fox is committed to camping. If fox mixes in approaches with camping, this will beat you out every time if you are stuck camping. So you need to revert from camping straight to defence with shielding, dodges, rolls and spacing to combat this change in playstyle.
In short, approach > camping; camping > defence; defence > approaches. But that is just for a couple of match-ups.
Against MK and Wario I think camping does not work to well. They just fly or air dodge past it all. I take those match-ups in the assumption that Wario and MK will always be making the approach against me. How do they approach though? Against Wario it will likely be in the air. Just counter it with some cooked mid and short tosses. Maybe throw in a Nair or mortar occasionally. Then when they get in close try to defend against there antics.
MK is a little harder as he can approach like wario or from the ground. I am still not sure how to go about this MU. If I hold a grenade I get grabbed, if I do not have one I get tornadoed then stuck recoverying for like 2 minutes.
