One thing that really annoys me is how long Sun and Moon take to load up on an older 3DS. That, and how long it takes to get into the GTS, plus the time it takes for evolution to happen. So while I am happy that all I need is two games and one system in order to get trade evolutions, the amount of time to cycle between the two is a little ridiculous, as while I was doing this to complete my Pokedex in Moon, I got sniped twice, with the second one being one that was really crucial. I also wish I could put up custom messages to tell people to not trade, but that probably would not help. I have done this for four generations now, ever since the GTS has been a thing, but for Sun and Moon it takes twice the time it has taken the others and it is the first time I really have been sniped.
