You do realize that the removal of l-canceling HURTS slower characters, right? The fact that faster characters land with almost no lag, while slower one land with huge amounts, makes them much worse than in Melee.
For example, if Fox's nair is 12 frames in Melee, 6 frames l-canceled, and Ganon's fair is 25 frames, 12 frames l-canceled, who benefits more (note: I don't know the actual frame data, this is just an example)? Ganondorf drops 13 frames, while Fox drops 6. Plus Fox's running speed is faster, giving him more maneuvrability.
If anything, the removal of AT's HURT slower characters. Except you wouldn't know that because you are a non-competitive noob.
