The things I hear that make me shake my head comes down to "The rules you play with are WRONG!!!"
I have heard this both from players who seem to believe that anything but 1 vs 1, no items, on stages deemed balanced enough somehow makes me terrible. I have also heard it from people who think turning items off is the wrong way to play and find it somehow offensive others do that.
I think the fact this game can have such a competitive scene, while also being a game I can take to family gatherings and play with the adults and kids alike shows how well made it is.
Furthermore, friends, family, and I have come up with rule sets that create challenges for the better players, and create chances to win for the newer players. This can't be done in games like Street Fighter, Soul Calliber, etc. At least not as well as it can be here.
Newer people not caring to even find out what apex is would burn out of competitive rules so quickly. . All they wanted was to hang out and have a good time and they are getting swept stock wise at least every other game. On the flip side, competitive players wouldn't want to touch the rule sets we use with their goals.
Point of a GAME is to have FUN... and this has a lot of good ways for different groups of people to do that. Personal preference is just that. And yes, some ways of playing could be deemed wrong for certain purposes but not simply wrong. There aren't many cases where I think telling someone "You are having fun wrong!" makes any sense.
