Dude, thank you for writing a samus guide! We really do need a new one to keep a little better pace with the changing meta. You have some good move descriptions. I think you could talk more about the utility of moves though. That and there's some mis-information/misnomers in the guide:
“Ability to crouch cancel is pretty good which helps Samus to stay at higher percents without being KO’d.”
The utility of crouch canceling isn’t survivability, its the ability to disrupt your opponents approach [they hit you to start a combo, you cc and retaliate instead]. And it doesn’t work at higher percents.
“Samus is heavy, so without proper DI, other characters can combo her or even zero to death with ease”
I’m pretty sure you need to at least reset once (and probably more than that) to kill samus. Not getting hit with combos is a strength for her.
“VERY little Oos options, so getting caught in shield pressure by Fox and Falco could mean potential danger”
Wavedash oos, nair oos, bomb oos, dropshield->lcancel, grab, spotdodge, roll if you can read an opening (bad, use rarely), jump if you read an opening (kind of bad but not as bad as roll). But most importantly upb. You should never get “caught” in spacie pressure. Upb and reset to neutral.
“[Jab1] Use this move as a way to convert to a downsmash or fsmash.”
This is hecka not guaranteed. The set-up exists in very specific situations and will get you punished more often than not. This is a bad thing to tell new people. Also jab shield pressure isn’t mentioned for jab1.
“[Jab2] does not provide the means for a follow-up attacks”
At certain percents this move straight up combos into ftilt and even if it doesn’t do that it will knock down most characters and set up a tech chase.
“[utilt] you can technically spike someone in the air with it”
What? No.
“[dsmash] Expect to be using this move a lot since it is one of Samus’s better moves.”
Most times where you could dsmash you should probably dtilt instead since it sets up punishes better. Dsmash is way laggy and new sami get punished a lot for using this move.
“[bombs] This move by itself is pretty useless”
Bombs are a powerful neutral game mix-up as well as a combo escape and form of shield pressure.
“[back-air] this move is quick”
Bair comes out on frame 9 which is relatively slow for an aerial.
“[down air] comes out pretty quickly”
Dair comes out on frame 18 which is VERY slow for an aerial. You also mention it being a meteor spike, which is misleading. Is it a meteor or a spike? Those are two different things. Also, this move is plus two on shield and is a ridiculous combo starter/extender.
But don't just take my word for it! Go ask questions on the samusboards and watch samus vids. I believe in you dude. Also it would be nice to have a neutral game section. And, as I mentioned you could mention more of the utilities of each move.
