Lasers aren't bad. They're just situational, as they probably should be compared to being broken. They're among the faster startup + travel speed projectiles in the game making them even landable at long range. A lot of situations where they can punish or be used in followups, just can't throw them out carelessly.
Blaster fires on frame 11, the same as Fox's Blaster, Sheik's fully charged Needles, Robin's Thunder, Elthunder, and Arcthunder, and just 2 frames faster than Ryu's Hadouken. Sheik's partially charged and uncharged Needles come out at frame 5 with 48 frames of end lag; fully charged, there's 54 frames of end lag. Yeah... Sheik... We need to talk.
So, it fires fast compared to Lucas's PK Fire (frame 21), Pikachu's Thunder Jolt (frame 19), (Dr.) Mario and Luigi's Fireball (frame 17), and the Pits (frame 20), but the end lag is what kills it. Luigi gets to act at frame 41, Lucas gets to act at frame 53, and funny enough, Ryu and Pikachu get to act at frame 58, but their projectiles just work differently. Lucas has good knockback on his PK Fire, Pikachu's TJ travels around like an annoying spring and hits at angles, Ryu's Hadouken can have altered travel speed, has a fairly large hitbox, and Shakunetsu hits multiple times. Falco has a linear, thin projectile that does set knockback in a way where it's not as useful as a single Needle from Sheik who does 1%, has less end lag, and I think has more range while causing some knockback - it's set for single Needles, right?
As of now, it's good for edgeguarding pretty much at max distance against slower characters along with tacking on damage. For distraction and approach purposes, it's not that great.
If you were actually paying attention, he never mentioned wanting sh laser back, as it's super braindead in brawl, just a 10 frame cut on the end lag of laser to contrast with the way other characters use their projectiles to cover their approach.
I think he was mocking ZeRo and not me.
