Alas, you have so much to learn here... You should've seen the Complaint thread before it was locked. 106 pages of complaining goodness. This? Really is nothing compared to that.
I wouldn't say you'd be hated for the comment... You DO have a point. What IS the point of complaining over characters? It sounds a bit obsessive. I guess why we DO complain is because... well... we enjoyed the characters. As you noted, you'd be upset if Sonic was gone. Thing is, WE are taking action for the characters that were cut. They were either too important to us, too good, something rather. We have our reasons.
You know people complained about Mewtwo, right? They made petitions, they complained, they wanted him out of the Smash series. Did it work? Not... necessarily. Mewtwo was GOING to return either way, but was probably cut for the sake of a newer Pkmn generation rep.
So, then, what's the point of complaining if we're probably not going to be heard? Well, perhaps we MIGHT be heard. You cannot ignore an angry mob of individuals whose favorite video game characters were cut. What we are missing are details. WHY exactly were they cut? All we have are speculations, speculations, speculations. We need answers. We need to know why we won't ever be able to Smash as such great characters ever again. I'm sure the majority of people here could agree with me that they want answers, and if you really think that pointing out the obvious fact that they're in Melee and we should play it (which I do, personally)... well... let's just say you're a LONG way from changing our minds.
Give us answers... legit, straight from the top answers... and we may, JUST may, quiet down.
Welcome, by the way.
