True Blue Warrior
Smash Hero
Even with the revival games, FE's cumulative sales (which is what people care about when criticising FE) isn't anywhere as big as Mario, Pokemon, Zelda or Donkey Kong. Zelda is bigger than Donkey Kong in this regard and BoTW is one of the top 3 Switch games in sales, which is not something that can be said for FE Awakening and Fates in relation to the 3DS.I respectfully disagree, while I do think Fire Emblem's size related to the backlash, it was the jump in Fire Emblem characters that caught everyone's eye. Going from 2 to 6 was the big deal for a lot of people. Likewise, seeing Zelda go from 5 to 9 would catch people off guard and make the guardians easy targets for "why didn't x get in when y did" syndrome.
Every other comment regarding disatisfaction with the roster would be "Why can't DK get 3 reps but Zelda can get 9?" or "Why didn't Bandana Waddle Dee get in but all 4 guardians did?". Considering Fire Emblem also underwent a revival around the time of SSB4 but still got comments complaining about oversaturation, it is unlikely the champions would get a free pass from anyone other than the most die-hard Zelda fans.
Zeds has always been an iconic Nintendo franchise since 1986 whereas FE only really got big relatively recently world-wide with Awakening and only had international releases since the early 2000's. For all these reasons, Zelda wouldn't get the same level of criticism as Fire Emblem.
