How is it possible that anyone can think Lucario and Mewtwo play similarly?
****, Lucario is closer to MARTH than he is Mewtwo. Mewtwo sets up combos with d-tilt, ***** fast fallers with fair chains, kills floaties with upthrow, uses nair as a sex kick (****ty sex kick, but still), ****ING TELEPORTS!, disables people with down B, gimps with bair, and does double jump cancel shenanigans ALL DAI!
Lucario's all about fairing, camping f-smashes and Aura spheres, and playing super duper keep away until he gets enough damage on him for his hits to actually matter.
And you people think Lucario plays like that....at all?
^^Rikana..not true. L-canceling has no fail window. You can spam it every other frame if you really want to.
Also, your idea doesn't give a reason NOT to L-cancel. It just makes it even more important not to mess up (which is already pretty ****ing important when you've got characters like Marth who basically jizzes himself when a Falco misses an L-cancel)
