**** you. Snake needs this. I mean, are you kidding me? They're the only things saving snake right now. The fact that it's hard to get him off his feet is why he isn't a character where people are screaming "buff buff buff!". Removing the range on those moves would destroy snake. Completely and utterly destroy him. Don't do it; he's balanced enough as is.
First off, chillax dude. All i did was propose nerfs to snake and then you respond like i beat you up and took your lunch money. Your entire tone throughout that post is incredibly childish and really didn't help to present much of an argument at all.
Lets look at the general goal of brawl plus. People who played brawl enough on a competitive level got sick of the camping, the planking, the defensive play, etc etc. So after the idea of brawl plus became viable, many people made changes to every character to make them quicker, low tiers more viable, and make offensive play and combos more commonplace. People miss the fast paced action of melee, and want to see that introduced to the cast and stages available in brawl. Simple enough.
I would say for the most part they have succeeded. Just about every character has much better offensive capabilities, many more combos, and move faster all in all. Characters that are probably still very heavily projectile based (read: campy, zoning, w/e you wanna call it. characters that need to force you to approach to thrive): snake, toon link, olimar, and rob. Other characters w/ good projectiles are still very good on the offense. Not to say that tl, oli, and rob are bad in cc, but once you get around the zoning projectiles, things become much easier, these characters have glaring weaknesses in cc, and make them fun to play against. Theres a reward for getting past the zoning.
Snake however, doesn't fit into this category. Throwing grenades and tripping c4's certainly does force EVERY character to approach snake, but heres what im getting at, this puts you in an arguably a worse position. Not that many characters have ways of getting around these two tilts, and find themselves losing to them constantly. Essentially what you get with this is snakes playing in a very cookie cutter style that nets them a very good result. All they have to do is place grenades all over the screen (a thrown grenade doing 5% w/o explosion, explostion doing what 13?), make use of their c4 to force bad situations, and then when the opponent is forced close, abuse the range and speed of the ftilt/utilt for the damage AND kill.
So, if you guys want to see snake players succeeding on a high level with 4 moves, then certainly, don't change snake. I can guarantee you it will be boring, and don't think people won't do this. If this game gets popular on a tournament level, we will see many people doing this to win, after all, play to win right?
If you don't want to see this, then reward what ally manages to do with snake on a pretty constant basis. Setups and combos with projectiles. I think it takes a lot of talent, and when done properly, certainly limits the opponents options. Im not saying completely nerf snake, but I think taking his game in a different direction would be a better idea then leaving it as is. Making his aerials a bit faster, weaker, and have less knockback would allow you to combo into grenades/c4s/dsmashes more often. Make the dsmash faster so setting it up isn't only possible between stocks. You don't need to make the tilts weaker, but certainly reducing the hitbox on the uptilt would give snake a bit more of a blindspot in cc, thus giving him the need to get out and start working w/ projectiles again.
Its really your choice, if snake players and everyone else want to see him be an incredibly boring character that probably only ally will be able to make use of, then sure, leave him as is.
