Says who?
Apparently right now Pokemon Trainer, Ness, and Ike are getting somewhere decently. All of them are D tier and lower.
And there is still the fact that Low tier tournies exist, so even if its the only reason its still a reason
I repeat, if low-tier tourneys did not exist, there would be no reason except for fanboyism to talk about anything below D-Tier. C-tier is already pushing it, but anyway-
The reason people are discussing the characters you mentioned is because some people actually believe that they should be moved up... up high enough that they should be in C-Tier and banned from low-tier play (I don't know why people would want to do this though, unless fanboyism and all that blah blah blah. Most of the Sonics were sadface
when we learned about how we can't make money except in the AN where he's still legal; which it shouldn't be, but just because statistics show otherwise, I'm going to be judged as wrong... Too bad, Ike is so much easier to pick up, be good with, and almost just as potent as Sonic if Sonic were allowed in said low-tier events).
Pokemon Trainer is the only character I believe deserving of such a promotion (but that's debatable, obviously), I'd guffaw at the thought of anybody telling me that Ness or Ike should be anything but low-tier material.
