I've been complaining about the removal of slide and charge in MM9 and MM10 as the primary example of the Mega Man 2 bandwagoning since 2008.
It's as close as you can get to the blatant 'because Mega Man 2 did it' mentality and was incredibly obvious pandering to anyone who realized they deliberately moved the needle on his move list back to a specific...point.
