Man, i just recently had a discussion about this on SRK the other day.
It seems that the majority of players from UMVC3 really have a lack of understanding of the game they play.
That is why we keep hearing stuff, from the very same players that the game allows for "random" stuff happening, lol.
UMVC3 is a game that allows a lot of BS so that is why we see a great pool of players lacking the understanding of many stuff of the game like the spacing game and fundamentals, since it allows them to bypass it by learning hit confirms into combos to get massive damage due the heavy damage nature of the game.
