Let me put it this way, the way the supporters of the Big Three conduct themselves is enough to turn me away from the Big Three. I didn't refuse to buy Brawl just because Little Mac, Duck Hunt Dog, Toad, Dixie Kong, Animal Crossing rep, Tingle, Meowth, Starfy, and Krystal didn't get in Brawl. I didn't boycott Brawl just because they cut Melee characters like Mewtwo and Roy and added more clones like Toon Link, Lucas, and Wolf. I didn't demand that Sakurai lose his job or wish pain and suffering upon Sakurai just because Sakurai made decisions that I didn't agree on. I still bought Brawl because I wanted to try out all these newcomers. Sure, I lost one of my mains (Mewtwo) but I found new and unexpected mains like Lucas, Wolf, R.O.B., Pit, and Meta Knight.
As for SSB4, it really sucks that I lost two of my mains (Lucas and Wolf) and three characters I had fun playing with items on (Ice Climbers, Squirtle, and Ivysaur)... but hey, I finally gained the chance to play as Little Mac, Duck Hunt Dog, Mega Man, Pac-Man, Villager, and Mii Fighters. I also get to try out new and unexpected characters like Wii Fit Trainer, Rosalina, Greninja, Palutena, Robin, Shulk, and Bowser Jr. It is likely that some of them are going to be my new mains. Just because I've been denied the opportunity to play as Toad and Dixie Kong in SSB4 is not going to stop me from playing SSB4 and discovering new favorites. I'll just move on and keep on supporting for Toad and Dixie Kong for Smash 5.
