I know that the ability to string attacks together was reduced from Melee to Brawl. I never stated otherwise. It was just .kr0's notion that there are absolutely no combos in the game that annoyed me. I am also aware that Lucas isn't the best combo character by a long shot, I was just saying that he has possibilities, and so has Marth, which was the initial point of the debate.
There really isn't. The "max" hit string I ever pulled off was like 5 with Zero suit (dthrow->upsmash->upB->dtilt->upair) but those are all based off the opponents MISTAKE. I don't consider IASA frame attacks chaining into one other move a "combo." (dashattack to dsmash with Diddy for example). I don't consider Marth's sword-dance (B->B->pause->another sword dance) a combo because you can get out it just by rolling.
Guranteed combos don't really exist. But you can string small chain of moves because the opponents aren't PERFECT and they can forget to DI, airdodge, or do any fast aerial to retaliate. Fox's sex kick->waveshine->upsmash or Falco's dair combos and stuff thats INESCAPABLE no longer exist in Brawl which I am really happy for.
The max "combo" that I pulled off with Lucas was like a downthrow->uptilt->uptilt and the guy could have gotten out of it if he just DIed to the right and airdodged the third tilt.
With Marth, he can string his sword dance to an fair but honestly, he can't follow up after his fair out of his upward sword dance hit with anything. Maybe he could do at most a three move combo (sword-dance, to fair to nair) but considering the slight range nerf he got and the non-existance hit stun and the broken airdodge mechanic, I highly doubt I'll see any "combos" that does more than 20% dmg.
The only character that can combo from what I've experienced was Toon Link and his bairs and D3's chainthrow (and D3's chainthrow doesn't work against like half of the characters)
