UgH yeah, especially on the GTS.... You really can't find a good offer anymore, everything has either been sniped or is someone asking for Hoopa >_>
Oh, same, it doesn't bother me. It could be a lot worse. The only thing I hate is like saving right before WTing every time @_@ I'm not entirely sure that's why it's so slow, but since Game Sync takes forever, I can only assume. You can actually see all of your GTS trades (and WT I think, too) if you have a PGL account! It's pretty cool. Yeah, I'm not really sure about previous games much either, but I remember trading was a huge hassle since you had to have the ones you needed to trade in your party. I've never traded in any games earlier than RSE, though, but yeah, trading is sooooo much easier than it ever was, it's unbelievable. Especially since you can do it ANYWHERE! It's great.
TBH I don't think they thought a lot of things through completely >_> *looks at GTS* Oh, me too, it just drives me nuts when my Pokemon aren't organised and whatnot. So besides the boxes I use I have one for Pokemon to Evolve, Pokemon with HAs, Pokemon with a few good IVs, Pokemon to Trade, and then Pokemon I like or use often like my HM slaves (terrible name ugh) HA really does make otherwise not useful Pokemon worth finding!
