They definately aren't the same, but there are definately properties that the two issues share, most of which is the *****y whining coming from people I wouldn't expect (M2K for Ledge-Camping, and OS for MK) to whine about something so trivial.They aren't the same, people should just beat the **** out of players who do this after tournaments.
Meta Knight is lame, but there's nothing I can do other than learn the matchup to its fullest and hope for the best (the best being that my opponent screws up).
Ledge Camping follows nearly the same process, albeit to more or less of a magnitude based on one's perception of the two issues.
