I feel the game has gotten alot more strategic in that not every character has all that wave dashing glitch stuff like melee did. Now you rely on your pure skill of the character you play. I think the game has gotten slower than melees and some characters advantages were watered down from melee. But i think it all game out to be a more dynamic game.
The game hasn't gotten any more strategic, it's just that most people couldn't think at Melee's speed... The game is by far less dynamic because of the lack of offensive options the game has and the multitude of broken defensive options there are to counter every offensive one (camping, shielding/shield grabbing, ROB's Dsmash and spot dodge for specific examples).
The characters are LESS balanced. The only good characters are the ones who can camp really well (Pit, ROB, Snake), the ones who have a way to discourage camping (Game and Watch, Lucas/Ness to an extent) and the ones who completely dominate the actual fighting with their high priority, strong attacks, etc. (Marth, Game and Watch, ROB, Snake kinda). Everyone else pretty much sucks (exaggeration, live with it. But I have a feeling if I don't put this here I'll get someone saying "BUT I BEAT PEOPLE WITH BOOZER ALL THE TIEM!").
If you didn't notice, that makes ROB and GW amazing in both offensive and defensive situations... While most arn't good in either. And Snake kinda, but his recovery sucks and his aerials are slow.
Some of you are saying that camping isn't a problem and will go away. What the hell makes you think that camping is a problem that will be overcome with an increase in skill. The problem is the lack of offensive options, not how physically hard it is to get past the projectiles. The game is SLOW and most of the projectiles carry very little lag afterwards. You go to punish them for it after taking a little percent by going through their projectiles, they shield, you get punished, and they resume camping. The REASON the shield works so well for someone camping is that usually to get through the projectiles you have to jump over them. Once you get to them, you're in the air, which means you can't grab. You can opt to land behind them, but then they'll just roll away, or drop their shield and punish you with something, since the shield drops so fast.
... Ok, that paragraph kinda died, I really didn't want to get into a hypothetical situation of what to do to overcome camping, but that's what happened... Main thing is, no risk, high reward. Why WOULDN'T you do it.
