Ok. I guess that's the reason.
Also, if Isaac gets in, who do you want to support next? Besides Hornet, I think I'll go support Takamaru or Saki.
Like many others, I dunno how much I would actively support other characters since Isaac is the character for me that makes me think I should never ask for anything again because I will have received the one character I wanted most since post-Melee.
If nothing else, I think I would turn to support the female characters who haven't got into the game. I saw the support thread for wanting more female characters recently and it really made me think about the number of female characters in the game and how many female characters I would love to see in Smash.
For example, Dixie Kong, Krystal, Impa, Midna, Mipha, Urbosa, Tetra, Shantae, Chun-Li, Tifa, and Yuna would all be high on my list and I am sure there would be more that I am willing to back. The more I think about it, Mipha and Chun-Li are probably tops for me. It astounds me we don't have more LoZ reps and the Champions from Breath of the Wild would be perfect. Urbosa is probably easier to imagine as a fighter, but Mipha was my favorite of the Champions. Chun-Li is fighting game royalty and I wouldn't mind seeing one more Street Fighter rep. I'm sure there would be a big argument to have M. Bison in over her, but I'm backing Chun-Li.
