Honestly there isnt a single character i can think of that can deal with proper falco laser spam. Its too good of a projectile, and thats just half of the problem. If you do find a way to get in close he just shines you away and repeats the process. There was a video in the falco forums about properly timing his lasers so they hit kirby, yea you could crouch underneath, but what is preventing the falco from just jumping over you?
Pit's arrows are another hugely gay projectile because of how frigin fast they are. You spam a few, then when they get close they just f.B, and that move is so fast as well that you pretty much have to roll way before they even think about doing it, and even then sometimes you'll still get caught by it. Sure he isnt as bad as T.link or Falco, but it is still very hard to get around. Not to mention he also has anti spam.
T.link as well has great projectile game and any smart player isnt going to just toss **** out there left and right as fast as they can. They are going to shoot a few arrows, while you're far away, once you get closer they will throw in the boomerang which makes SH over arrows pretty stupid looking, then if you get past his boomerang he'll probably have a bomb waiting for you, and after all that frustration to finally get in close no matter if you are a space animal or frigin bowser. Then you have to deal with that ****ing sword of his.
Out of the three listed here i dont think any character has any really good approach or answer to any of it. You could go through the frustration, but with the lack of hit stun after you get 40% from projectiles to nab a grab or a lucky smash for 12-20% they can just go right back to spamming their **** at you. so thats probably another 40% tacked on and another 12-20% for them again. So already you are at 80-40 max, and its been about a minute and a half of gameplay. The only real way to get around the massive spammage is heavy brawl it seems. The reason they are so good is because half of the time the character is spent recovering from throwing something is time you spend hovering in the air from getting hit by it.
Spamming is just too good in brawl and i dont foresee any AT in the future of normal brawl to counteract it. It takes very little skill, and has an extremely high pay off. We have to find a new way to take it out or brawl will die quickly. Every tournament will have nothing but Robs, T.links, Pits, snakes (lulz), and MKs which will get really boring really quick. Other character will be seen, but with no chance of winning.
Wow thats alot longer than i expected it to be. Sorry i rambled a little to much. D:
