Let me start off by saying, I'm really happy y'all decided to post. I found quite a variety of opinions. I am pleased. No matter how much I disagree, you have the right to speak. (Or type, in this case.)
To those who agree with me: Thumbs up. The second we were able to Wonder Trade, we should've had the option to rename unsatisfactory nicknames from ppl we've never even met. Someday, that sentiment will become reality.
To those who said that nicknames are fine and that I should breed: You guys are half-right. It's not the freedom to nickname I'm against, and it's certainly not others' freedoms either. It's about my own preference. I prefer non-nicknames. And I HAVE thought about breeding. Except I'm not going to get a Golem, am I? So my dilemma has weight to it. My only hope is to befriend someone who has Alolan Gravelers or hope for a non-nicknamed Golem through Wonder Trade. I breed EVERY rare type I get. (As far as my uncomplete Dex is concerned. Oh and praise to GF for letting us Sun/Moon players catch a Ditto, yay!)
Oh, super glad I don't need Pokemon outside of Alola. Discriminitory, but makes my Dex Goal that much easier, unlike X/Y and AS/OR.
