In a way, no one is actually mad at a character. Did Lucas go up to Sakurai and ask 'Hey, can I be put back in Smash 4'? No. Sakurai and whoever else is in charge of adding and creating characters chose to add Lucas. Heck, this complaint can go to characters from the base game too. Many people thought Ike would be cut but he got in. What if you don't like Lucario or Falco or Toon Link or etc. Maybe you feel they shouldn't have gotten in over Wolf or any other character you support. Any anger people feel is towards Sakurai and co and their decision to add whoever but not Wolf. There's no reason to feel actual anger towards a character when it comes to Smash. Go ahead and hate Porky for the **** he's done to Ness and Lucas in the Mother games. Go ahead and hate Ganondorf for all the **** he's done to Hyrule. But to hate them as a character in Smash is pointless.
I still believe Wolf is coming but to have to wait more than a year since the game's release to play as him is ridiculous.
Also, we were asked to rate the dlc so far and we did. Positive and negative feedback was given for each and every character. Not every character has to be liked or even tolerated. I do, however, agree that the supporters should not be attacked, not as a whole at least. If a few Ridley supporters or Bandana Dee or Krystal etc supporters were *******s to you, then sure, go ahead and hate them, but to label the entire support base for that character based on a few bad and vocal eggs is a bad idea.
Heck, I'm a great example. I'm rather vocal about my disliking of Wolf not being in yet and I'm also quite vulgar. What if someone chose to hate every Wolf supporter because they saw what I'm like? Is that fair to any of you?
